After several days of reports of a Dusky Flycatcher down at a local park, I went there myself to try to find it. After 45 minutes without luck, the Merlin app on my phone finally alerted me to a possible Dusky Flycatcher. I had just heard and photographed a Hammond's Flycatcher a bit downhill from where I was, but this possible Dusky was uphill from me. After making my way there I was able to locate the Dusky Flycatcher! I got very lucky with my first few shots of it. I stood there for a while and watched it move around to a few different perches, and I even returned a few hours later to see it again, but it didn't return to a close perch again.
While similar to a Hammond's Flycatcher, after reviewing the photos it has enough small differences to be confidently identified. My "North American Flycatchers" book, by Lee and Birch from last year, is a great reference. The sounds I recorded using the Merlin app were clearly distinct as well.
This was a fun lifer to add to the list! I was lucky enough to find it on my first attempt, which doesn't happen often.

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.
