I just witnessed some unusual (to me, at least) downy woodpecker behavior at my suet log.
Usually these birds are solitary, serial feeders, and they will chase each other away from the log, allowing only one to feed at a time. But this morning, I noticed that a male and female arrived together, the male taking an upper perch, and the female staking out a perch below and to the right of the male.
What surprised me was that the male started to feed the female. He would take a piece of suet cake, turnaround and down, and pass it to the female, similar to what I've heard about--but never witnessed--with Northern Cardinals. They repeated this behavior at least four times. Then they both flew off together in the same direction, with the male holding a large piece of suet cake in its mouth. I'm assuming that they have a nest with chicks somehwre nearby.
