This gallery is for several days' worth of birding. I got a Hermit Thrush photo I really quite like, in the rain. An improvement was made for my best shot of a Eurasian Collared-Dove, though still not a great shot. The first (and likely only) Golden-crowned Sparrows of the year for my yard made an appearance. Most importantly, I got my first shots of an Orange-crowned Warbler. I've used the Merlin app to identified them nearby, by song alone, many times without having seen one. On successive days I saw one down on the forest floor just before sunset and then at home through the kitchen window. The photos from home are terrible but I'm glad I finally got them!

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.
