Shoot 2023-10-27-144932

I again made a couple trips out to look for American Pipit, and again didn't find any. Still, I got some nice photos. At home, I saw a Great Blue Heron fly by a window. It perched up in a large tree for a moment, and I was able to photograph it. There isn't any water habitat at the house here, so I've only seen Herons stop twice briefly before moving on: once on a rooftop and now in a tree.

My "birds in review" collages can be found here.

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. This blog post has more details.
