This is a desert tortoise:
These are the fruit of prickly pears. Around here they are called TUNAS. Most birds and animals love them:
This video shows a desert tortoise eating a tuna. YUM!
Three weeks ago, my roving buddy and I were walking the Saguaro Discovery Trail at Tohono Chul Park looking for a nighthawk nest we had heard about. Suddenly, a lesser nighthawk erupted from the ground and flew several feet away.
We did some research and learned that nighthawks usually lay two eggs. The chicks are semi-precocial, meaning that they can move about after they are hatched, but depend on parental care till they fledge, 17 days later. How can almost-helpless baby birds survive 17 days on the hot desert floor? The answer is that they are invisible!
These two amazing photos were taken by photographer John Durham and are used with his permission. He took them in the Altar Valley, somewhat southwest of Tucson.
