Captain Sam's
We had another good day at Captain Sam's with 171 new birds and 16 recaptures of 24 different species. We captured the first Northern Flicker (in fact we got two) and Wilson's Warbler of the season. Northern Flickers are present around the banding station in the fall and winter but are seldom captured in the nets. They are a large woodpecker, and because our nets are designed to capture smaller birds, they have a tendency to bounce out of the nets.
Woodpeckers have a complex molt strategy and can have multiple generations of feathers within the same feather tract. Because of this, we are able to age most woodpeckers with a little more precision than other songbirds. In the fall, second-year birds will have a mix of replaced and unreplaced primary coverts like in the photo below. Notice that the outer two primary coverts are much darker than the inner ones. In hatch-years, all the primary coverts would be uniform and brownish like the inner five feathers in the photo below. Alternatively, if the feathers were uniformly dark, we would be able to age this bird as an after-second year, making it at least 3 years old.
The winds have shifted a bit from the northwest (last night) to the west (tonight). The current radar is showing good movements of birds along the coast and inland. A westerly wind should bring us birds more birds that are migrating more inland as they will be pushed toward the coast.

Little Bear
Another busy day at Little Bear brought us 109 new birds and just 4 recaptures of 22 species. Common Yellowthroats continue to be abundant, but we also had a surprising number of White-eyed Vireos and our first-of-season Wood Thrush. Among the other usual species, we also caught one Worm-eating Warbler, and one very drab hatch-year Cape May Warbler, two species we had earlier in the season but haven't seen in a few weeks.

A comparison of eye color on these two White-eyed Vireos. The hatch-year (left) has a dull, gray eye, while the after hatch-year (right) has the bright "white" eye that gives this species its name.
