Thanks to those who are helping Bird Safe Philly by reporting window strike victims on our iNaturalist project page. There are three buildings downtown, not along any of our formal monitoring routes, that could use extra eyes if you happen to live, work, or just find yourself passing near any of them. They are: Giant, 60 North 23rd St 19103; Condo (still under construction), 2100 Hamilton St. 19130; and the Kimmel Center,300 S Broad St. 19102

Some good news is that most of the birds being picked up by monitors and brought in to the Schuylkill Center are being released after 24 hours.
Remember that (quoting the veterinarian from the Schuylkill Center), “If one can pick up a bird, then it should go to rehab.”
Field Trips: Linda Widdop
Participants must follow all the COVID-19 Guidelines as posted on the website and must sign a participant release to attend the field trip.

Navin Sasikumar – 2021 iNaturalist City Nature Challenge [CNC]
Philadelphia’s official numbers were:
While not officially a competition this year, those numbers put us at 11th in observations, 12th in species, and 11th in observers out of 419 participating cities. Well done, Philly!
And despite not being a competition, we take a little bit of pride in that we beat New York City in all 3 categories. Washington, DC smoked us this year with 43k observations, nearly 3k species, and 1961 participants, but we’ll get them next year! A big thank you to everyone who participated and helped make our third time a grand success. And we hope you’ll join us again to achieve that goal in 2022. Thanks to everyone who submitted photos and audio recordings for the CNC.

Ours was the 15th eBird checklist for the island. We detected 52 species (32 more than the previous high total!): https://ebird.org/checklist/S86925858. This added 26 species to the hotspot list.

Martin Dellwo: With audio recording identified as Purple Finch yesterday and today, the Rittenhouse Square hotspot checklist officially passes the century mark, 100 species. 80 Species are documented by photos, and 50 with audio recordings. With the Purple Finch, at least 81% have either a photo or audio. I’ve seen 87 of the species. 30 species were added since May 1 2020, which I consider the unofficial start of what I’ve been calling my pandemic project. On that day I added Canada Warbler, Brown Thrasher, and Great-crested Flycatcher to the list, the previous new entry being in September 2019. It’s been fun and fascinating, but mostly it goes to show, you can bird just about anywhere! Recent interesting finds include a gorgeous male Cape May Warbler, a Marsh Wren (still there), a Northern Waterthrush, Blue-gray Gnatcatcher, American Woodcock, and a lingering female Yellow-bellied Sapsucker. Northern Parula, Black-throated Blue, Black-throated Green, Black-and-white warbler, Common Yellowthroat, American Redstart, Magnolia Warbler, and Ovenbirds.
