We had nice weather, but it was very quiet today at Marymoor. A few species were singing constantly: Willow Flycatcher, Western Wood-Pewee, Bewick's and Marsh Wrens, Swainson's Thrush, and Common Yellowthroat, but there wasn't a whole lot else. Even those species were not very easy to see. Still, we walked the loop slowly and carefully, and managed to find some birds.

Highlights:

Canada Goose                   Flight lessons for young birds
Cooper's Hawk                 Only our 2nd since April. With prey.
Barn Owl                           Matt had 4-5, including babies near the windmill, early
Cassin's Vireo                    One singing, near dog swim beach 3
N. Rough-winged Swallow 1-2 near grass soccer fields
Brewer's Blackbird             1 female on grass soccer fields
American Beaver                1 in slough at swim beach 3

The CANADA GEESE were learning to do the over-and-back half barrel roll used to "dump air", allowing a quick drop in altitude. This was a family-sized group, and there was no particular reason to be using that flight technique where they were flying, which was fairly low over the weir.

We had both WARBLING VIREO and YELLOW WARBLER feeding BROWN-HEADED COWBIRDS.

For the day, 56 species. BREWER'S BLACKBIRD appears to be new for our 2012 list.
