NOTES: (Breeding Status: Territorial unknown. Behav. Context: Nest invitation. Gen. Climate: Arid. Cover Density: Medium.) The male arrives in the spring and hunts suitable nest holes which are generally in sycamores but can be in oaks or even a conifer if the cavity is large enough. When a female arrives, they begin so-called "hole hunting." I don't know if they are pair bonded at this time but perhaps not since I have observed a female and 2 males calling in competition (for the female or for the territory?). He offers--she selects and she probably tries more than one. The call is very muted and throaty. She may also call, the same type of call.
By the way, no nest was made here.
