I wrapped up July with several birding outings.
I got my best-ever shots of a Bald Eagle, and Rhinoceros Auklet, at the coast. I also got to see a parent Common Murre feeding a large fish to its youngster. They were calling out to each other a lot, presumably because they can't see each other when on the surface, due to the waves.
I got a chance to go up for some higher elevation birding the following day. I was specifically looking for Clark's Nutcracker, Hermit Warbler, Canada Jay, and other high-elevation species. I briefly heard a pair of Clark's Nutcrackers at the top of some trees, but they soon flew away. I very briefly saw the silhouette of one as it flew from one tree to another, but obviously I would have liked to get a photo. Still, they made it onto my checklist and thus my life list.
I then waited until dusk at Salt Creek Falls. I clearly heard a new lifer, Common Nighthawk, of which I saw at least four. I was also looking for Black Swift, which were supposed to be nesting there behind the waterfall. I wasn't able to positively distinguish the Swifts from the Nighthawks while standing there, but upon reviewing the photos on the computer it looks like I did in fact photograph at least one Black Swift as well. Some birds did appear to have a different overall "gestalt" of wing shape and wing motion but unfortunately I have to rely on the photos when adding Black Swift to my life list.

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.
