[Birdnet] Re: Light and dark Logan gulls

[Jason Pietrzak]

Upon further review I'm wondering if Slaty-backed could be considered
for that dark gull... The head has less streaking on it than my guides
show for Black-backed and the eye streak is fairly prominent although
I don't know if that's a reliable field mark. I checked through photos
and couldn't find anything with the legs visible... I guess I might go
back to the playa before dark.
