Bucks County Pennsylvania CBC

For the last 5 years or so I've had the "Bucks County" CBC on my "to-do" list, intrigued by the thousands of Herrings seen at the Tullytown Landfill. On Saturday, 15 December 2018, I joined George Armistead and Jason Weckstein for a jaw-dropping day at the dump, estimating some 35,000 Herring Gulls for the day.

Tally: 4 Glaucous, 8 Iceland, 25 Lessers, 450 Greats, 600 Ring-billeds, ~35,000 Herring Gulls.

1st Cycle Glaucous with Adult Great Black-backed.

Putative, adult, Lesser Black-backed x Herring Gull. 1 of 6 seen on this day.

Yes, in my zone...gull patrol is not for everyone.
