I twice went out to a grassland area looking for a Grasshopper Sparrow among the Savannah Sparrows. I didn't find one. I saw at least one sparrow without much streaking on the breast and flanks, but it had a pronounced light-colored malar stripe and its head and bill seemed too small for Grasshopper Sparrow. I came away with nice photos of a Savannah Sparrow though.
I also noticed, on my second outing, a small gull with a small black bill and a black spot behind its eye. It looked like a new bird to me but I wasn't sure since there were also Black Terns flying around, and they can look similar when they're not mostly black. Upon further review it turned out to be a Bonaparte's Gull, a new lifer!

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.
