For this shoot, I took a short walk through a meadow with tall grasses and wildflowers until I arrived at a small stream. I returned to this location because a few days earlier the Merlin app on my phone, using its bird sound ID feature, had identified a potential new lifer for me: House Wren. Luckily enough, when I returned, the House Wrens were still in the area and still making noise, allowing me to find them easily. As I suspected, there were several fledglings and adults.
I had my camera with me on this time, and was able to get a few average shots of some. I also got some shots of a flycatcher, which I presume is a Western Wood-Pewee. The Merlin app identified a Pewee as well as an Olive-Sided Flycatcher as well, but this wasn't one of those. No other flycatchers were identified by song so I'm pretty sure the one I photographed was a Pewee and not one of the more uncommon identical-looking birds. The Olive-Sided Flycatcher I heard was also a new lifer.
As I stood near the stream, a crew of loud-talking men was slowing advancing through the tall grass, apparently spraying for invasive plant species. Since I'd rather not inhale herbicides and I couldn't hear the birds anyway, I had to leave earlier than I would have liked. I still came away with two new lifers!

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.
