I've been rushing to get my NFL Elo project into the phase that requires a lot of number crunching before the weather heats up. I was finally able to do that recently and get back to some photos from the middle of last month.
My favorite encounters here were a singing Bewick's Wren, a curious Hutton's Vireo in the same spot that came right up to check me out, and a pair of Fox Sparrows looking for food among the leaf litter.

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.
