Jackson Bottom birds: April 3-9, 2010


Heavy rains during the week flooded most of the wetlands and trails.

At least one brood of Canada Geese goslings were hatched before the flooding, but perhaps most eggs were destroyed by the waters. The geese that lost clutches of eggs to flooding will probably attempt nesting again when the waters subside.

American Robins and Bushtits are building nests. The Great Blue Heron colony has birds sitting on nests and a Red-tailed Hawk is nesting in the Douglas-fir grove with them. The Bald Eagles are still sitting on eggs, but they have been under quite a bit of harassment from other eagles passing through. It may be two weeks before we know if the eggs are going to hatch. The Great Horned Owl chick has been seen on branches up to 15 feet away from the nest, getting ready to fledge.

Due to limited access, barely over 60 species of birds were detected this week, instead of the 80 something of last week.
