This was an unusually good morning of birding at our house. I've seen American Robins all over town all year, but never in our yard until today. I also saw a Spotted Towhee in our yard for the first time since December 1st. Best of all, I got photos of a new lifer, the Red Crossbill. There was a group of them at the very top of a large douglas fir.

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.
