Again just birding at the house, I got a new lifer, Vaux's Swift, and decent shots of a European Starling (likely one of them that invaded the Flicker nest cavity).

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.

Vaux's SwiftThe Merlin iPhone app repeatedly identified Vaux's Swift calling, and there were 3 of them flying very fast over the neighborhood for a while. It was not easy to point the camera up between all the trees to get a shot of one in flight, but I think in this shot the bird is identifiable as a Vaux's Swift.
