Mid-April to early May marks the start of the breeding season for many birds in this neck of the woods. The male Red-breasted Nuthatch, having caught the eye of a female, performs as follows: he turns his back on the lady (seems non-productive), points his head in the air, droops his wings, and sways from side to side. This doesn't sound very alluring but maybe it helps him to 'shake his booty' in a sexy way. Appearances notwithstanding, it seems to work quite well, as there are always plenty of Red-breasted Nuthatches about. The male feeds the female, both on and off the nest, and both parents feed the nestlings. They seem content to raise just one brood a year. Sounds all very dutiful and practical to me, which is good because we all need lots of nuthatches around and about, to entertain us.
