We were birding along Patagonia Lake State park several days ago and encountered and recorded a bird call we could not identify. It was consistently at 2.8 kHz with 2-9 flat, ear, ear, ear calls. We chased it from trees along the edge of the southeast side of the large steep rounded bridge up the hill into the campground where we lost it unfortunately. We never saw it. Merlin called it a Black-crested Titmouse, and the sonogram matches quite well, but that is not an AZ bird, so likely something else. I am considering Great tailed grackle, but have not found a sonogram that matches very well. I have uploaded three of the wav files we have:
Unk bird 1 - Bewick's first then the target bird Unk bird 2 Unk bird 3
