I agree! I think the song variations of many birds such the mountain/western bluebirds, and black-capped/mountain chickadee etc. are VERY similar. I sure wouldn't be reliable identifying the difference in the field! I just hope the person who recorded the audio files we used was an expert!Celestial-Howl wrote: I was going to say Mountain Bluebird, but I couldn't find a decent call to confirm it so I went with Western Bluebird because they sounded very alike.
EDIT: Are there Blue Jays? I think I heard one.
We were surprised that there aren't really bluejays in Yellowstone, according to their bird list (which was also too bad because we had a nice animation model for a bluejay). We did choose one bird from that family that is abundant...and LOUD.
