This is two separate dates. A Cooper's Hawk in our yard (glaring at a cat) from one day, then a walk down by the ponds from a couple days later. Nothing terribly interesting but I did finally see and photograph my first Savannah Sparrow.

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.
