Highlights of the 78 birds banded on Saturday, September 18 included 4 Ruby-throated Hummingbirds and 2 Yellow-bellied Flycatchers. As noted above, thrushes were a major component of the migration, which allowed the photo below of 3 species (Veery, Gray-cheeked, and Swainson's) to be taken by one of our volunteers. The number of Swainson's Thrushes was also a single day record, breaking last week's record of 20, with 40 today!

It was an OK day for warblers, with 16 individuals of 7 species banded, including Nashville, Magnolia, Blackpoll, American Redstart, Ovenbird, Northern Waterthrush, and Common Yellowthroat.
Interesting birds observed but not banded included a first-year Bald Eagle flying over, a Red-breasted Nuthatch that has been hanging around the banding station for a couple weeks, a flyover American Pipit, and additional warblers including Yellow-rumped and Black-and-white.
Highlights of the 58 birds banded on Thursday, September 22 included 3 Ruby-throated Hummingbirds and a Hairy Woodpecker; a species uncommonly captured at this site.

Although very few sparrows have been captured so far, an indication that the migration is shifting away from warblers was the season's first Brown Creeper.

And thrushes continued strong today, with a record of 14 Gray-cheeked Thrushes; the old record was 12 at the previous Point Rosa site.

The season's first Yellow-rumped Warbler was a further indication that the warbler migration is more than half over, although several later migrating species should continue into early October.

Interesting birds observed, but not captured today included Black-throated Green, Palm, and Bay-breasted Warblers, and the season's first White-throated Sparrow.
Highlights of the 70 birds banded on Sunday, September 25 included 1 Ruby-throated Hummingbird, and a very infrequently captured species, a hatch-year Yellow-bellied Sapsucker. I'm pretty sure it can be called a female as it only had a single red feather on its forehead, but did not show any white (or red) feathers on the throat, so maybe should be left as sex unknown?

The peak of Blue Jay migration in this area is from about September 20 - October 15, so it wasn't surprising that we caught the first one of the season today.

Other later season migrants were also captured today for the first time this fall, including Eastern Phoebe and Ruby-crowned Kinglet.

It was another good day for thrushes, with 13 Gray-cheeked and 30 Swainson's, both of which would have been record days only a couple weeks ago! And right on schedule (though eBird thinks they were late), my near-annual capture of Wood Thrushes in late September, with two today.

Right on schedule were two Orange-crowned Warblers.

And a bit overdue, though some years we don't capture any, was a Bay-breasted Warbler.

Compare this undertail shot of the Bay-breasted, showing buffier flanks and undertail coverts, with the undertail shot of the Blackpoll Warbler I included in the last post which shows yellower flanks and bright white undertail coverts.

Interesting birds observed, but not banded, included an Osprey that circled over the banding area and adjacent parking lot ponds most of the day.

There was also a modest hawk migration today, with 3 Sharp-shinned, 3 Cooper's (together), 20 Broad-winged, and at least 2 Red-tailed Hawks. Also seen were the season's first Golden-crowned Kinglets, a Brown Thrasher, Yellow-rumped Warblers, American Redstart, and a couple of Rose-breasted Grosbeaks.
Banding could not have been done on any of these days without the capable assistance of the following volunteers: John Bieganowski, Terri Chapdelaine, Mike Charlebois, Stevie Kuroda, Gary Ladowski, Robin Ladowski, Dave Lancaster, Ava Lau, Harry Lau, Tim Mann, Bruce Watson, and Blanche Wicke.
