Patagonia, AZ, USA
By surprise, I found another bluebird nestbox occupied and now has eggs in it. I have not spotted any bird frequenting the box, and did not expect it to be occupied, since the location has some foot traffic, so I am not sure what bird it is. In the close by car port, there is a pair of Say’s Phoebe nesting on a beam. (Recurring over the years).
I have two other bluebird boxes which are occupied by dusky-capped and ash-throated flycatchers.
Please see pics of the eggs and location of the nestbox. Thanks.
