I'm still on the hunt for new-to-me gulls this winter. I haven't found any yet but it's been fun learning to ID them better.

The above hashes-<date>.txt
file contains SHA-256 hashes of all the photos
from this shoot. The hashes-<date>.txt.sig
is a signature of that hashes
file, created with my PGP key. The signature file
itself was written to both the Bitcoin Cash and Algorand blockchains, in the
OP RETURN
and Note
fields respectively, using the transactions below.
In short, this proves that these photos and the signature both existed at the time the
transactions were written to the Bitcoin Cash and Algorand blockchains.
This blog post has more details.

American Herring GullThe gray color on the head and bill size and shape rule out Western Gull for this one. I think the bill may work for both Thayer's and American Herring, but the underside of the far wing is black where Thayer's would be much lighter. This bird seems to be growing out its primaries, but for a Thayer's we'd still see some white-tipped long "tongues" on some of the full-length primaries. That leaves this as an American Herring Gull.

Surf Scoter, Black ScoterI don't know how often seals/sealions hunt scoters but I noticed the Surf Scoter on the left really getting out of the way!

Western x Glaucous-winged Gull (hybrid)The wingtips are too dark compared to the back, so I think that rules out "pure" Glaucous-winged.

Western GullThe orbital is the same color as the bill: deep orange-ish yellow. The eye appears a bit bright but it's very well lit by the sun here and Western Gull does have some variation in eye color.
