Possible Herring x Lesser Black-backed Gull? Pennsylvania (USA), 21 Feb. (1 Viewer)

Hello all,

Back to my photos, which are awful with my current phone. Unfortunately the birds were also quite distant, at least 400m off. I did have good views through scope at 60X, though.

Two birds here. I'll try and post sets of each one. Bird #1, I think, may be a 3rd-winter Lesser Black-backed with paler mantle (I've seen and posted about that here before). Would love any opinions still, but it didn't jump out too much and I thought it had too much marking on the bill for adult.

Bird #2 stood out immediately due to mantle color. The times it was awake, I thought the face/head pattern (and wingtips) indicated full adult. Through the scope, the bird's legs were a dirty pinkish color, different from both the Herring and LBBGs next to it (adults). Size was nearly identical to LBBG, maybe a bit on the small size even. I wonder if this is a mark against hybrid.

Photos below are of bird 1. No problem if nothing can be done due to pic quality here.

Now for Bird #2. The blurriest photo is only to show how color appearance changed with lighting. My phone darkened most of the pics except for this one, which best shows the color seen in the field.
