Saturday, April 22 was Earth Day. It was also planned to be a National day of protest, the "March for Science". Since I was banding, I made up my signs (from the Union of Concerned Scientists), and posted them on the banding station for the day. So, I did what I could...
Highlights of the 80 birds of 16 species banded today included the recapture of a Hairy Woodpecker, a species that is very infrequently banded in the park, which was originally banded here in 2015.

Another infrequently captured species is White-breasted Nuthatch. We probably don't catch many here, nor at the former location in Point Rosa Marsh, as the nets are generally not near very many larger trees, and the nuthatches don't spend much time in shrubby habitat.

An excellent number of Ruby-crowned Kinglets (18) was banded today, and it was a bit of a surprise to catch the first Yellow Warbler of the season which was record early by one day.

| Second-year male Yellow Warbler |
Another, more expected species of warbler was also captured today, two Palm Warblers. Based on the measured extent of chestnut on their crowns, which has a limited reliability, one was a male and one was female.

By noon, the wind had become a major frustration, even blowing my "Stand Up for Science" signs off the canopy, even hurling one at high speed right at my head! A minor frustration was a Belted Kingfisher that flew up and down the channel, eventually landing on one of the poles holding up the mist nets...

Interesting birds observed, but not banded, included the continuing American Bittern calling from the North Marsh (and possibly a second bird calling from the South Marsh), a Sandhill Crane flyover, and 2 Golden-crowned Kinglets which were somewhat late.
Highlights of the 49 birds of 16 species banded on Sunday, April 23 included the first Blue Jay of the season, as well as the first House Wren banded, although one has been singing in the banding area since April 2.

Interesting birds observed, but not banded, included a calling American Bittern, a flyover Sharp-shinned Hawk.
Highlights of the 106 birds of 21 species banded on Friday, April 28, included a bunch of Blue Jays (10), and the first but perhaps overdue Blue-gray Gnatcatcher of the season.

And it was a fairly good warbler day for this early in the season with 5 species captured: Nashville (2), Yellow (3), Yellow-rumped (16), Palm (3), Northern Waterthrush (1), and Common Yellowthroat (1).

It was also a good day for sparrows, with Swamp (6), White-throated (14), and the first Lincoln's (3) of the season. Lincoln's Sparrow will always make the photo highlights on my banding blog, as it is one of my favorite sparrows no matter how common they can be.

Interesting birds observed, but not banded today included a calling American Bittern, this time only from the South Marsh, several flyover Gadwall, a Cooper's Hawk in a display flight, and singing Warbling Vireo, Black-throated Green Warbler, and Baltimore Oriole.
I would like to thank all the volunteers who helped with banding on these three days, including: John Bieganowski, Stevie Kuroda, Harry Lau, Rose Lau, Ava Lau, Tessa Lau, Matthew Porter, Kristin Porter, Anne Ross, Holly Marie Todaro, Bruce Watson, and Blanche Wicke.
