Why do woodpeckers drum on a metal box? It is all about territory. Their rhythm can be distinctive for their species, saying "I am male, big and strong so stay out of my territory." It also serves to attract a female although the sexual attraction of a male beating its head against a metal surface is a turn-on that escapes me.
"Really interesting thing about red-bellied woodpeckers. The female hatches the chick, and the male, as you are watching, is feeding the young chick after it has fledged. This is common behavior among woodpeckers."Reviewing the video I can see that this is a rather drab chick with no red like an adult female. By now the juvenile is flying and able to run up and down a tree like an adult. It either can't get its own food or chooses to wait and be fed. Any of you parents can relate to this behavior.

- "Mate-feeding has evolved more often in species in which the female incubates and builds the nest alone and have noncarnivorous diets. This suggests that mate-feeding is a behavioral strategy that compensates for nutritional limitations of females during breeding, as both incubation and nest building are energetically costly processes, and noncarnivorous diets are deficient in proteins"
- "Incubation feeding has evolved more often in species that place nests at elevated sites, suggesting that these species face low predation risk that allows males to feed females. In the particular case of incubation feeding, we found that species that have evolved this behavior produce larger clutch size and have higher hatching success."
In the video you can see the adult male getting seed from the feeders, then storing some in the bark of trees and delivering others to a rather drab appearing juvenile high in a distant dead tree branch. Now that you know what is going on, feel free to watch the video again to catch the quick beak-to-beak feeding.
