Alaska |
This cam is the result of a partnership between the Hancock Wildlife Foundation in British Columbia and the American Bald Eagle Foundation in Haines, Alaska. The pair raised two fledglings in 2007, nested in a different location in 2008, and raised two fledglings in 2009.
Based on past experience, look for eggs in early May, chicks in early to mid June, and fledging in late August or early September. |

This nest is located in a tree in a small park in a residential area of Burnaby, BC. It's unusual not only for being is such a populated area, but for being in a tree with leaves that hide the nest (parents generally seem to prefer an unobstructed view from the nest), and for being several miles from the nearest body of water large enough to catch fish. This nest successfully fledged 2 eaglets in 2007, and fledged 2 eaglets in 2008, though one had poor feather development on its wings, making us wonder how that would affect its survival.

This pair either abandoned their nest or were driven off by a nearby pair in 2007, but returned in 2008 to raise two eaglets. The older one fledged successfully, but the younger one fell from the nest when he was almost 11 weeks. He was found and taken to the Orphaned WildLife Rehabilitation Society (O.W.L.), where he was found to have no major injuries, but was underweight so they admitted him. He was released about 5 weeks later. Eagles believed to be his sister and one of their parents were seen in the area until he was released, at which time they all disappeared - we like to think heading North together for the salmon runs. The nest had fallen apart quite a bit by the end of the 2008 nesting season, and wasn't substantially rebuilt for 2009. The pair laid two eggs, both of which hatched. The older eaglet fell to its death when part of the nest broke away when he was about 3-1/2 weeks old; the younger eaglet (nicknamed "Bandit" on the Hancock Wildlife forum) fledged prematurely when a branch broke off the tree when he was about 11 weeks old, and was taken to O.W.L. for rehabilitation, and subsequently released at Chehalis in the fall, when there were other eagles in the area.
This pair had eggs in early April and chicks in early-mid May, but nearby eagles had chicks in early April - so there may be some flexibility in nesting time in the area. |

British Columbia |
This nest is located in the same general area of Delta, British Columbia, as the Orphaned WildLife Rehabilitation Society (O.W.L.), which cared for Delta Dan, who fell out of the Delta 1 nest in 2008 and needed some extra help to get ready for the fall migration. This nest was new in 2008, and while the pair built a nest and spent time there, they did not lay any eggs (not uncommon for the first year of a new nest). They laid two eggs in 2009, but sadly the eggs did not hatch, although they continued to incubate for at least two weeks past the likely hatching time. Part of the nest collapsed as they were rebuilding it for the 2010 season, and they've divided their time between trying to fix it, trying to start a new nest, and possibly being a bit lost (though that's assigning human characteristics). A raccoon has been seen in their nest several times, adding to the difficulty of rebuilding it for the 2010 season.
Based on other nests in the area, eggs could come any time from late February to mid April. |

The nest is located about 30 meters (100 feet) up an evergreen tree, and is situated on private property about 100 meters from the ocean on Hornby Island in the Strait of Georgia between Vancouver Island and the British Columbia mainland. According to Doug Carrick, the eagles built their first nest in the fall of 1989 and fledged their first eaglet in 1990. This will be their twenty-first year of nesting; they have fledged 18 eaglets in 20 years - just under one a year, which is considered average for eagles in this area. There has been a camera in the nest since September 2004, and it was first connected to the internet in spring 2006. The pair laid two eggs in 2006, neither of which hatched; the camera was offline in 2007 after the line was damaged in a winter storm but Doug reported that they raised and fledged two eaglets (Thunder and Lightning) that year; they did not lay any eggs in 2008. In 2009, they laid two eggs, both of which hatched; the younger eaglet Echo died in a freak accident, after becoming tangled in the female's feathers; older eaglet Hope fledged successfully. Based on past experience, look for eggs in late March, chicks in late April, and fledging in mid to late July. |

This pair fledged 2 eaglets, named Victoria and Sidney, in 2006. They laid two eggs in 2007, one of which hatched and successfully fledged; that eaglet was named Skye. This pair was observed building a feeding platform in 2007, which they made into a second nest that they used for 2008; attempts to place cameras in the alternative nest were unsuccessful - the tree was too high for the crane - so information for 2008 was provided by observers on the ground - who reported the successful fledging of three eaglets, named Sunny, Angel and Freddy. In 2009, there was a wide angle cam in each tree, and they again used the "new" nest, successfully fledging three eaglet, named Breeze, Hero, and Tiny/Tink.
Based on past experience, look for eggs in early to mid March, chicks in mid April, and fledging in mid to late July. |

Male K93 (produced by the San Francisco Zoo in 1999 and released from the Bullrush Hacktower on Catalina Island) and female A32 (removed from a nest near Juneau, Alaska, in 2004 and released from the North Hacktower on Santa Cruz) became a pair in 2007. Dr. Sharpe and Steffani of IWS built them an artificial nest in December 2007 because they hadn't had much luck with nest building; they added branches and used it as a feeding platform, but did not lay any eggs in 2008. They built a nice new nest for 2009, but did not lay any eggs. In 2010, A32 was replaced by A37 (produced by the San Francisco Zoo in 2005 and released from the South Hacktower on Santa Cruz) - and the pair laid their first egg ever! |

Adults K65(M) & K56(F) Male K65 was removed from a nest near Steep, Vancouver Island, BC, in 1986 and released from the Bullrush Hacktower on Catalina Island; female K92 was raised at the San Francisco Zoo in 1999 and released on Catalina Island from the Bullrush Hacktower. This pair was allowed to keep their eggs in 2007 (instead of having them removed for incubation), and both hatched - making them the first pair of chicks to hatch naturally without human assistance on Catalina Island since 1945; males K00 and male K71 both fledged successfully, but K71 was found dead in September. The pair laid two eggs in 2008; both hatched and male K70 and female K71 fledged successfully, but K71 was found dead July 24, probably of starvation; K70 was still on Catalina Island as of January 2009. (There were two K71s because numbers of eagles that die are reused; it was a coincidence that the number was used again at the same nest.). There was apparently a change of partners at the beginning of 2009, with female K56 becoming K65's new mate. We don't know what might have happened, only that K92 has not been seen. K56 was from an egg laid at Seal Rocks, taken to IWS for incubation, and then fostered back into the Seal Rocks nest in 2005. The new pair laid two eggs in 2009; one was lost a week or so before its hatch date and the other produced female K99, who fledged successfully but was sadly lost 2 months later, probably while trying to fly to the mainland. The Catalina eaglets are given short-range GPS units when they're banded so they can be tracked by IWS staff - if the staff is close to the eaglet; once they fly off to other islands or the mainland, they can no longer be traced, and even on Catalina, the person with the receiver has to get fairly close to an eaglet to pick up its signal. Because of the remote location of the Pinnacle Rock nest, it's unlikely that a cam will be placed there.
Based on past experience, look for eggs in late February and early March, chicks in early April, and fledging from mid-June to early July. |

adults K80(M) and K47(F) This is a relatively new nest with male K80 (who came from an egg laid at the San Francisco Zoo and fostered into the West End nest in 1998) and female K47 (produced at the San Francisco Zoo in 2004 and fostered into the Seal Rocks nest). They nested and laid eggs in both 2008 and 2009, but the eggs disappeared shortly after they were laid both years. It seems that the instinct to incubate the eggs isn't quite as strong as the instinct to produce and lay them, especially for male K80. |

adults K25(M) & K34(F) Male K25 was hatched from an egg removed from the West End Nest in 1992 and fostered into the Pinnacle Rock Nest; female K34 was raised at the San Francisco Zoo in 1993 and released on Catalina Island from the Bullrush Hacktower. This pair was allowed to keep their eggs in 2007 (instead of having them removed for incubation), and both hatched - making them the second pair of chicks to hatch naturally without human assistance on Catalina Island since 1945 (Pinnacle Rock was first, a week earlier); female K03 and male K77 both fledged successfully; K77 was last seen on Catalina Island in November 2007, and probably explored neighboring islands until June 2008, when he drowned while trying to fly to the mainland. The pair laid two eggs in 2008; one broke after about 10 days, and the other hatched to become male K62 Gulliver; he fledged successfully, but drowned about 4 months later while trying to fly to the mainland. 2008 was the first year IWS has a cam on this nest; the eagles moved their nest for 2009 so there wasn't a cam in 2009 and won't be a way to have a cam in 2010. They did lay two eggs in 2009, but only one hatched, becoming male K90, who fledged successfully.
Based on past experience, look for eggs in late February and early March, chicks in early April, and fledging from mid-June to early July. |

adults K33(M) & K17(F) Male K33 was hatched from an egg removed from the Seal Rocks Nest in 1992 and fostered back into the Seal Rocks Nest; female K17 was brought from a nest in California as a chick in 1984 and released on Catalina Island from the Bullrush Hacktower. Both of the eggs removed for incubation in 2007 hatched, and the pair successfully raised K75 and K76 (both males). K75 was the only 2007 eaglet still on Catalina Island as of December 5, 2007. In 2008, this pair was allowed to hatch their eggs naturally for the first time. It's not known how many eggs were laid, but two hatched, and males K88 and K89 fledged successfully. K88 was sighted on the mainland August 19 and was seen in southwest Oregon in November 2008 and back on Catalina Island in March 2009; K-89 died around Sept 6 while trying to fly to the mainland. They laid two eggs again in 2009, and successfully fledged males K-96 and K-94. K-96 died while trying to fly to the mainland; as far as we know, K-94 is OK, though he hasn't been seen for a while.
Based on past experience, look for eggs in late February and early March, chicks in early April, and fledging from mid-June to early July. |

adults K81(M) and K82(F) The male K81 was hatched at the San Francisco Zoo in 1998 and fostered into the West End Nest, while the female K82 hatched from an egg removed from the West End Nest in 1998 and fostered into the Pinnacle Rock Nest; like most of the Catalina adults, they are generally referred to by their wing tag numbers instead of a nickname. They became a breeding pair in 2003, and K82 has laid six eggs from 2004 through 2007, five of which have hatched. Because of problems with DDT pollution which can make the shell of eggs too thin to hatch naturally, eggs from this nest are removed a few days after they are laid, replaced with artificial eggs, and placed in an incubator; when they hatch, the chicks are returned to the nest. This pair raised two eaglets, male K78 ("Sol") and female K79 ("Luna"), from the two eggs they laid in 2007. They laid two eggs in 2008, both of which were removed for incubation; one died shortly before hatching, while the other hatched and was returned to the nest, becoming female K83 ("Star"); she fledged successfully. In 2009, it was decided that there were enough productive nests on Catalina Island that the eggs would not be removed for incubation, and both their eggs hatched naturally! Females "Thunder" and "Lightning" both fledged successfully, and were both still on the island as of October 2009. Catalina cams are streaming video using flash technology; there's also an option to watch still pictures updating at 5 second or 20 second intervals if traffic at the site is heavy. The cams are solar powered, so the picture may be less than optimal in bad weather.
Based on past experience, look for eggs in late February and early March, chicks in early April, and fledging from mid-June to early July. |

adults K01(M) & Wray (F) This nest, established in 1991, is unusual in that it had three adults for a number of years. The female Dianna (K69) has wing tag on each wing and female Wray (no wing tags,but has a silver leg band) were brought from nests in British Columbia as chicks in 1986 and released together from the Sweetwater Hacktower on Catalina Island. Male K01 (sometimes called "Superman" ) was hatched at the San Francisco Zoo in 2000 and fostered into the Pinnacle Rock Nest; he replaced the previous male who disappeared before the 2006 nesting season at an age of 25. Dianna has not been seen since early in 2008, and there is hope she may have left to form a pair with an unattached male. According to Dr. Sharpe of IWS, Wray and the original male were a pair for a year before Dianna joined them, so she was the junior member of the trio. 22 chicks have fledged from this nest since 1991. Three of the five eggs removed for incubation in 2007 hatched, and the trio successfully raised female K72 ("Earth" ) and males K73 ("Wind" ) and K74 ("Fire" ). One of two eggs removed for incubation in 2008 hatched (though it was out of position for hatching and needed assistance to break out of its shell), and Wray surprised everyone by laying a third egg after the initial two were removed - which actually hatched naturally, although Dr. Sharpe put the chances of an egg from that pair surviving to hatch at less than 5% because of the contamination in the area. Both the incubator chick K65 "Miracle" and the naturally-hatched K67 "Surprise" are female. In 2009, both eggs were left in the nest, both hatched, and K98 "Faith" and K97 "Joy" (both female) fledged successfully, though K98 was found dead in the water 5 weeks later, perhaps while trying to fly to the mainland; K97's transmitter malfunctioned shortly after installation making her hard to track after she left the nest area; she was last seen on the island in late August 2009.
Based on past experience, look for eggs in late February and early March, chicks in early April, and fledging from mid-June to early July. |

adults A00(M) & A16(F) Male A00 (produced by the San Francisco Zoo in 2002 and released from the North Hacktower, Santa Cruz) and female A16 (removed from a nest near Juneau, Alaska, in 2003 and released from the South Hacktower, Santa Cruz) have been a pair since 2007 and may have done some work on a nest, but haven't laid any eggs yet. |

adults A40(M) & possibly A49(F) "Cruz" Male A40 (produced by the San Francisco Zoo in 2005 and released from the South Hacktower on Santa Cruz) and female A24 (removed from a nest near Juneau, Alaska, in 2004 and released from the South Hacktower on Santa Cruz) were seen together in the Fraser area in the spring of 2009, and it was hoped they'd develop into a breeding pair. Then in February 2010, A40 was seen with a different female, A49 "Cruz" (hatched in 2006, becoming the first naturally hatched eagle on Santa Cruz in 50 years). This is potentially a new pair and it's not clear if they're ready to nest yet - though Cruz's mother A26 was only four when she laid the egg that became Cruz. |

adults A46(M) "Stephen Jr." & possibly A24(F) Male A46 (produced by the San Francisco Zoo in 2006 and released from the North Hacktower on Santa Cruz) and female A24 (removed from a nest near Juneau, Alaska, in 2004 and released from the South Hacktower on Santa Cruz) were seen together in mid-March 2010; A24 was formerly the mate of A40 at Fraser. This is a new pair and it's not clear if they're ready to nest yet. |

adults K11(M) & A17(F) The Grasslands nest was established in 2006 by male K11 (produced by the San Francisco Zoo in 2001 and fostered into the West End nest on Catalina Island) and female A04 (removed from a nest near Juneau, Alaska, in 2002 and released from the North Hacktower on Santa Cruz Island), and is one of the few known bald eagle ground nests in the lower 48 states. They had a successful first year, raising A60, the second chick hatched in the wild on Santa Cruz in 50 years (A49 Cruz at Pelican Harbor was the first), but have not repeated that success. The crew from the Institute for Wildlife Studies (which monitors nests on Catalina and Santa Cruz Islands) found a broken egg in the nest in 2007, and in 2008 two chicks hatched but did not survive. Female A04 also died, most likely of injuries sustained while defending her chicks, probably from another eagle. K11 was later seen with female A17, who was removed from a nest near Juneau, Alaska, in 2003 and released from the South Hacktower on Santa Cruz. They were seen building a nest in a tree in 2009, but did not produce any eggs. They still seem to be a pair, so we'll see what happens next. |

adults K10(M) & K26(F) The parents were both hatched in the San Francisco Zoo (male K10 in 2001 and female K26 in 2002) and then fostered into nests on Catalina Island (K10 in the Twin Rocks Nest and K26 in the West End Nest). K26 laid two eggs in 2006 (one hatched, becoming the female A49 "Cruz," the first eagle chick to hatch in the wild on the Channel Islands since 1949; on Santa Rosa as of February 2009); two eggs in 2007 (one hatched, becoming male A63 "Limuw," who died about 7 weeks after fledging while scavenging roadkill in Nevada), and two eggs in 2008 (both hatched, becoming A65 "Skye" and A64 "Spirit" - both male; both were knocked from their nest by a juvenile eagle when they were about 6-1/2 weeks old, taken to the mainland for rehab and released from a hacking tower; Skye drowned after becoming entangled in a kelp bed; Spirit was on Santa Rosa as of February 2009). The pair also had two eggs in 2009; both hatched, but the chicks died shortly after hatching from unknown causes. K10 and K26 are a strong young pair, so we're hoping this year will be better.
Based on past experience, look for eggs in the first half of March, chicks in mid-April, and fledging in late June or early July. |

adults A28(M) & A27(F) The Sauces pair consisted of male A28 (removed from a nest near Juneau, Alaska, in 2004 and released from the South Hacktower on Santa Cruz) and female A02 (produced by the San Francisco Zoo in 2002 and released from the North Hacktower on Santa Cruz). They nested in 2008 and laid at least one egg, but the nest failed. They tried again in 2009, laid eggs, were seen incubating - but were found away from the nest around the time the eggs would have been expected to hatch. Then in July 2009, IWS received a report that A02 was found dead in Pozo, which I think is quite a ways inland on the mainland. It looks as if A28 has paired up with female A27 (also removed from a nest near Juneau, Alaska, in 2004 and released from the South Hacktower on Santa Cruz), and they're working on a nest for the 2010 nesting season. |

They were a non-breeding pair in 2009. |

They laid an egg again in 2009, and again it didn't hatch. [It was removed for testing - need to look for results.] We're hoping for better luck in 2010. |

adults Patriot (M) and Liberty(F) The California Department of Transportation tried to relocate this nest in 2008 because of major highway construction planned for the area, putting a large cone in the nest to keep the eagles from nesting. The eagles had other ideas. People rallied around, and eventually the highway department removed the cone, and the eagle couple - named Patriot (M) and Liberty(F) - successfully fledged two eaglets (named Freedom and Conehead) in 2008, for a total of five eaglets in three years. They laid three eggs in 2009; all hatched, and the three eaglets (named Freedom, Hope and Spirit in a contest sponsored by local media) fledged successfully. Based on past experience, look for eggs in early to mid February, hatching in mid March, and fledgling in mid to late June. |

There are four cams on this nest, two overhead and the other two looking from the side; the intent is to have one of each online, with the other as backup, but both overhead cams failed early in the nesting season; they streamed both side view cams for a while, but are now down to one sideview cam. They are continuing to try to add sound, but still haven't succeeded at that. The cam is solar-powered, so will be shut down from dusk to dawn to conserve power and might be a bit uncertain on very dark days. There are also photos for the day saved in four-minute increments, so you can see what has happened in the previous 24 hours. The cam is often offline during the fall and winter, and is back online in February.
Based on past experience, look for eggs in the first half of March, chicks in mid-April, and fledging in early July. |

| Iowa Decorah |
This nest was featured on the Nature show "American Eagle" - and now you can watch it live! The nest is in Decorah, Iowa; the exact location is not publicized to protect the eagles. Local time is Central time. The pair has been observed since 2002 - you can read the Nest Diaries online at the Iowa Natural Heritage Foundation website - but 2009 was its first year online. They successfully raised three eaglets in 2009.
Based past experience for this pair, look for eggs in the first half of March, chicks in mid-April, and fledging in early July. |

Maine I |
The cam is located in coastal Hancock County, and is streaming video with sound. It has infrared for night viewing, although that may be turned off during the off season, and is a pan-tilt-zoom to allow closeups of the chicks when they're small. The eagles have nested at this site for 13 years and raised 20 offspring, making them one of the most successful pairs in Maine. They fledged two eaglets on cam in 2006 (a third chick was lost, likely due to sibling rivalry), but had tragedy in 2007 - the weather was brutal right after the chicks hatched and they lost them; they did not lay eggs in 2008 or 2009. Eagles have been seen at the nest regularly in 2010, though it's not certain if this is the pair from earlier years or if a change occurred at some point since the loss of the chicks in 2007.
Based on past experience, look for eggs in the first half of March, chicks in mid-April, and fledging in early July. |

Maine II |
The cam is located in central Maine, and according to BioDiversity Research Institute (BRI) the nest has been occupied every year since 2001 (and the territory has been used at least on and off for the last 30 or more years). 2009 was the first year there were cams on the nest. There are two cams, one looking at the nest from the side, and the other over the nest looking in. Both have night vision and constant 15-second refresh views; BRI was hoping to stream from one of the cams, but so far has not had much success with that, and the side view cam apparently failed just before the first egg was laid in 2010. The cams use satellite internet, so the connection may be slow at times. The pair successfully raised two chicks in 2009.
Based on other nests in the general area, look for eggs in the last half of March, chicks towards the end of April, and fledging in late July. |

Maryland |
The camera has frequently updating still shots, and uses infrared technology to provide "night vision." It is generally offline once the fledglings leave until midwinter. It is also turned off from 11 pm - 3 am to reduce bandwidth expenses. The nest is located about 80 feet up in the air in a tree in the Blackwater National Wildlife Refuge in Cambridge on Maryland's Eastern Shore. This is one of the first nests to have a camera, and has been online since 2005. The pair has successfully raised three chicks in 2005 and two in 2006, 2007, 2008 and 2009.
Based on past experience, look for eggs in late January, chicks in early March, and fledging in mid to late May. |

Massachusetts |
Barton Island is a small island in the Connecticut River, near Barton Cove, in Gill, Massachusetts. A female eagle originally raised and released at the nearby Quabbin Reservoir in 1985 paired with a male bird released in 1986, forming the Barton Island territory in 1989. The original male was subsequently replaced (in 1996?) by a male with leg bands indicating it came from New York State. The nest has produced one or two chicks most years since 1989, although there were three years that the pair was unsuccessful (1997, 1999 and 2001). They fledged two chicks in 2002, one in 2003, two in 2004, one in 2005, two in 2006 and 2007, and one in 2008. The nest tree below collapsed at the end of the 2008 nesting season (eaglet and parents were fine).
They are now nesting in a red oak nearby, but they established their nest too late for a camera to be added for the 2009 nesting season. As far as we know, they didn't actually raise any eaglets in 2009 - though the nest is a long way from the nearest vantage point. The utility was going to try to get the cam operational for 2010, but they have a very small window to visit the island and the weather hasn't cooperated. |

Montana |
Libby Dam is located on the on the Kootenai River in northwestern Montana. The nest, also known as the Souse Gulch Eagle Nest, was established in 1996, with the first eggs in 1997. From 1997 through 2008, the pair fledged 21 eaglets, including two in 2007 and two in 2008. They laid two eggs in 2009 and both hatched, but the younger chick died when it was almost 3 weeks old (not easy to guess why on a refresh cam); the older chick fledged successfully.
Based on past experience, look for eggs in mid to late March, chicks in late April, and fledging in mid July. |

This nest has streaming video, with a good view of the nest, though the focus is a little fuzzy.
Based on past experience, look for eggs in late February, chicks in early April, and fledging in late June or early July. |

North Carolina |
adults Derek(M) and Savannah(F) This nest has a refresh cam that refreshes every five seconds; it's only on during daylight hours. Derek and Savannah are non-releasable eagles who have been at the Carolina Raptor Center since 1998. They became a pair, and she laid her first eggs in 2004. They didn't hatch, but in 2006 two eggs hatched; the eaglets were taken to a hacking tower when they were 6 weeks old and subsequently fledged; they have GPS units and can be tracked at the Carolina Raptor Center Eagle Tracking Project. They had one egg hatch in 2008, and that chick was also successfully fledged from a hacking tower. No eggs hatched in 2009; they think the unusually cold weather was responsible, and responded by insulating the pair's preferred nestbox (which is on the ground). They laid three eggs in 2010; the first egg hatched and the chick is looking good; the second hatched but the chick was not strong enough to survive, and the third failed before hatching. There are five other adult eagles at CRC, and I think most of them share the enclosure with Derek and Savannah, though they know better than to come close to the nest.
Based on past experience, look for eggs in early January and chicks in mid-February; chicks will likely be moved to a hacking tower around the end of March and should fledge from there in mid-May. |

This nest has streaming video with one cam mounted above the nest, and the other at a distance looking up at the nest in its tree. The nest is on Sooner Lake, near Stillwater in north-central Oklahoma. This pair's former nest was on an artificial tower erected by the Sutton Avian Research Center and local utility OG&E to replace the original dead nest tree used by this pair after it fell down. The pair first built a nest in the dead tree in 1995, and laid their first eggs in 1996. Since then, they've fledged 24 eaglets, with three eaglets in 2000 and 2002. 2008 was the first year they've known how many eggs were laid; they do know that three eggs hatched in 2007, but the youngest chick was unable to compete for food with its older siblings, so only two of them fledged. There was an unusual clutch of four eggs laid in 2008, but the cam was down for a month shortly after they started to hatch, so we don't know how many of them hatched; there were two eaglets when the cam came back, and both fledged successfully. They laid three eggs in 2009, but only one hatched; the eaglet fledged successfully. In 2010 the pair did some preliminary work on two alternative nests, eventually choosing one in a tree near the lake.
Based on past experience, look for eggs in early February, chicks in mid March, and fledging in late May or early June. |

This is a streaming cam with a 3-minute limit; there's a brief intro before you get to the cam. Based on past experience, look for eggs in mid-April, chicks in late May, and fledging in mid to late August. |

The cam is streaming but doesn't have sound. Liberty and Justice, a pair of non-releasable Bald Eagles - female Liberty can only see out of one eye so lacks the depth perception needed to hunt in the wild, while male Justice was found with shotgun pellets in a foot and wing, resulting in permanent injuries that would keep him from hunting successfully. They bonded as a pair in 1993, and have successfully raised 14 of their own offspring and several foster chicks for release to the wild from hacking towers in Tennessee. Their three eggs were infertile in 2005; bad weather caused the collapse of their nest and loss of three eggs in 2006; and the one egg Liberty laid in 2007 was infertile - but in 2008 one of the two eggs she laid hatched, and Liberty and Justice successfully raised the resulting eaglet. They laid three eggs in 2009 but none hatched.
Based on past experience, look for eggs in late March, chicks in early May, and fledging in mid to late July. The chicks will be removed from the parents at about 5 or 6 weeks of age and transferred to a nearby artificial nest in a hack tower, where they will be released a few weeks later as part of the American Eagle Foundation's captive release program. |

This is a streaming camera with night vision (but not sound - it's near an airport so it's felt we'd hear more planes than eagles). The nest is in a botanical garden in Norfolk, Virginia. The 2007 nest fell apart after the last chick fledged, and the eagles built a new nest for 2008; NBG moved the cam to the new nest. This pair successfully raised 3 chicks in 2006 and 2007; in 2008, practically everything that could happen did - they produced 2 (or maybe 3) eggs, but then a four-year-old female started harassing the pair, forcing them from the nest for prolonged periods and leaving the eggs uncovered; eventually the parents appeared to abandon the nest, and two no-longer-viable eggs were recovered. Then the original female returned to the nest and was seen mating with the male - and a month or so after the initial clutch, they produced two eggs - which were apparently broken when the nesting parent jumped up to respond to a large bird (maybe a great horned owl) flying near the nest. The next day she laid the third egg of the second clutch - which successfully hatched. When the chick was about 3 weeks old, a photographer noticed a growth on its beak - and the chick was removed from the nest a few days later for testing; the eaglet (named Easter on this forum and Buddy and Poink on others) was found to have Avian Pox and was taken to the Wildlife Center of Virginia (WCV) for treatment. The treatment was successful, but Easter/Buddy's beak was damaged by the pox, and in August 2009 WCV declared that he was non-releasable, “based on a review of the bird’s treatment over the past 15 month, evaluation of the curvature of the eagle’s beak, and the habituation of this young bird to humans.” His beak will continue to need periodic trimming for the rest of his life, so WVC is now considering options for the best placement for Easter/Buddy as an educational bird. 2009 was a much less eventful year; the eagles moved back and rebuilt their former nest, and successfully raised three eaglets. The middle eaglet, nicknamed Azalea, was fitted with a transmitter, and you can follow her travels at http://eagletrak.blogs.wm.edu.
Based on past experience, look for eggs in the first half of February, chicks in mid-March, and fledging in early June. |

This nest is about 90 feet up a tall cottonwood tree, and you can see a bit of Lake Meridian in the distance. The eagles are named Star (female) and Spirit (male), and they've raised 16 eaglets over the past eight years, including two in 2007. The nest collapsed at the end of the 2007 season;

This cam is now streaming, with night vision! And it was repositioned in 2009 so there is a better look into the nest bowl. The Washington Department of Fish and Wildlife posted the following in 2008 about this cam: “This year we have retired the Puget Sound EagleCam and replaced it with the Lake Washington EagleCam. Located in a 100 foot tall Douglas fir tree, the bald eagle pair have been actively building their nest and should be able to be observed increasingly as the mating season and pair-bonding is upon us. This bald eagle cam was installed with a landowner’s invitation and cooperation and with the hope to share the unique views and interactions of a dramatically situated bald eagle nest.” Lake Washington is in the northwest corner of Washington state, not really all that far from Seattle. This cam was new in 2008, and there were two chicks that year, one of which fledged successfully and the other which died of unknown causes when it was 8-1/2 weeks old (the cam was refresh-only the first year, making it harder to see what was happening in the nest). They successfully raised and fledged two chicks in 2009.
Based on previous experience, look for eggs in mid-March, chicks in late April, and fledging in mid July. |

This cam was only online one season, in 2007. The pair laid two eggs, one of which hatched. One of the more interesting things we observed is that the second egg was still in the nest seven weeks after the other egg hatched, and the eaglet appeared to be brooding it from time to time.

There is a still cam that refreshes every 30 seconds and is on 24 hours a day, and also streaming video with sound during the nesting season. Liberty and Belle have been in this location near the Potomac River since late 2002, built their nest mostly in late 2003 and early 2004, and Belle laid her first egg February 14, 2004. The pair raised two chicks in 2004, one in 2005 and three in 2006; they had three eggs in 2007 but none survived the spring storms; they raised three chicks in 2008; they laid three eggs in 2009, but only one hatched - and that chick fledged successfully. In 2010 there was a major snowstorm with over 20" of snow after Belle laid her first two eggs; she kept them covered through the storm, but the snow was piled so high around the nest cup that the eggs were buried shortly after the storm ended. They cleared a new area of the nest and Belle laid a third egg - and there was another foot of snow shortly thereafter; that egg was left uncovered, apparently sitting on snow, a number of times over the next couple of days. It seemed as if Liberty was having trouble getting down to the nest cup (which still had substantial piles of snow around it), so sometimes stood guard rather than incubating. Immediately after the second storm, they started bringing in more sticks and padding for the nest area - and four days after the third egg, Belle laid a fourth egg. It's now been four weeks since the fourth egg was laid, and Belle and Liberty have been faithfully incubating, so we are hoping it will hatch (only one egg remains; we assume/hope it was the less viable third egg that disappeared after two weeks).
Based on past experience, look for eggs in the first half of February, chicks in mid-March, and fledging in early June. |
