On this morning outing I saw and photographed three lifers: Red-shouldered Hawk, Lincoln's Sparrow, and American Kestrel. I've seen quite a few Kestrels while driving around but not while birding. This Kestrel was hunting and flying back and forth between a tree and a power/phone line, and I was able to get some decent shots.

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.
