Unidentified Urosaurus Lizard


Hot patio near dense cover; no big trees nearby.


I photographed this Urosaurus lizard at the Boyce Thompson Arboretum in Pinal Co. It's either an Ornate Tree or Long-tailed Brush Lizard. I am having a little difficulty in identifying it. Help would be appreciated.

Kestrels are practically the size of Mourning Doves and Peregrines are larger than Cooper's. It's probably a Sharp-shinned, but I can't tell from the photo.

This bird is probably not a merlin because of it's coloration. I am more inclined to think that it is a sharpie due to the tail tips ending in black.It was smaller than a coopers and look at the eye too. Not a peregrine or kestrel?

Hi! Nice to talk again. I've been extremely busy with college but decided to check on how PN is doing. Your bird very well might be a Merlin, but can you rule out Cooper's or Sharp-shinned Hawk?
