When I read about Gila Monsters, it said they ate bird eggs. I thought about quail, since they nest on the ground. WRONG! Yesterday afternoon there was one in the front yard. When we went out to look, he proceeded to climb the mesquite tree. Very agile, too. When he was about 15 feet up, he stopped in a crook of the tree and looked down at us. Yep, this guy is going for the big eggs, no tiny quail eggs for him! Look out you big birds, your nests are no longer safe! Will upload a picture soon.
