I took advantage of the Brownsville CBC to bird at the Brownsville Sanitary Landfill (aka the dump). Since I was asked for photos of the Lesser Black-backed Gulls and am temporarily unable to crop or edit pics I decided to post them here. Here's a mob of hungry gulls.
And here's two Lesser Black-backed Gulls. I'm the first to admit one isn't 100% identifiable here, but the dark first winter to the right of the adult Lesser (that slaty colored bird on the left) is a Lesser as well.
And here's another bird. I had five total individuals for the CBC, with distinctive plumage features or age differences from the other birds.
