From the head pattern its Princess on the nestledge, can't see the 2nd bird however. She does not look impressed with the vegetation on the nest ledge, she is standing still just looking at the weeds.
For those of you who are asking "what vegetation"? After the chicks fledged, all that lovely fertilizer "poop art" resulted in an amazing mass of green plant material by August. I think Princess is a wee bit perturbed at what has happened on her patio. Hopefully this will improve the value of the condo nestbox!!
