I haven’t able to get a shot with both of them working on the same nest but they sometimes do. When they do it seems like one usually is the builder and the other is support item delivery (I’m imagining a tv surgical bit, with “twig” said like “scalpel”)
I think there’s 4 starter nests all along this beam.
I’m giving space and not using the DSLR during this fragile early construction phase because it spooked them once and I feel real bad about that.
Better view our one window. Birb on a beam holding a bent twig. They have a black upper body, face, and Mohawk (crest) visible from this angle. There are oak leaves in the background.
View of two windows, each with a Jay working on a starter nest.
