I took this photo on Dec. 18, 2023 in Aravaipa Canyon, a wilderness area that skirts the northern edge of the Galiuro Mts. of southern Arizona.
The deer was calmly browsing at the water's edge when it suddenly got buzzed by a Great Blue Heron. The huge bird startled the deer, which spun around and ran a very short distance before calming down again and going back to eating. I saw a number of other deer in Aravaipa Canyon but this is the only photo worth sharing.
