I suggested that this might be bird week, then there is this. The goldfinch knocked for admittance to our living room. Repeatedly. And over quite a stretch of time. The bird would fly away for a time, but then it would return and knock yet again. No idea what the attraction was.
Running an errand, stopped at stop sign, spotted this. Camera beside me, but by the time I opened the shutter this bird was almost gone. But it was one big bird!
