On the nest

Two and a half miles east of Quitobaquito on the South Puerto Blanco Road is a tall Saguaro with a nest.



If you stop to look, you will see that it is occupied.  Someone is sitting on the nest even in these warm days so there must be eggs.



What is it?  Much discussion has been had among rangers and volunteers about the identification of the bird. 

Large bird.  Large ears sticking up.




Some say a Long Eared Owl





Some say a Great Horned Owl.



Could be either one.  What do you think?
