Seal Rocks, Catalina Island, CA

Most pictures are from the Institute for Wildlife Studies forum,
primarily from the forum IWS Updates


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.

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. 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. 2008 was the first year IWS has a cam on this nest; the eagles moved their nest for 2009 so there won't be a cam this year.

This is the general area around the nest, but I'm not sure where exactly the nest is.

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.

Summary of 2009 Season:

The adult eagles weren't seen in their nest this winter, although they appeared to be together as a pair and were frequently seen in their territory. And on March 4, Dr. Sharpe reported he'd found their new nest, several hundred feet below the previous one, and they were incubating two eggs. He did not think it was feasable to put a camera on the new nest, at least this year.

All images are the property of the cam from which they were taken and/or the person credited.
Thank you for letting me use the images for this compilation.
