Shoot 2025-01-15-062817

Some great birds have been visiting my neck of the woods, and I was able to get out to see them. A cooperative Costa's Hummingbird was the easiest to see. He appeared after just a few minutes waiting near a feeder, much easier than last January's Costa's. And as a bonus a local birder pointed out where a Barrow's Goldeneye has been hanging out in the river.

I wasn't quite as lucky with the American Tree Sparrow. I first went to find this common eastern species and came up empty. When I returned a couple days later I was able to find it, and managed to get decent photos despite the bright overcast conditions.

Lastly, on the following day, I spotted my target Lewis's Woodpecker after standing out in the cold for an hour. Another great bird!

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.
