A few weeks ago a female Yellow-bellied Sapsucker drilled numerous rows
of holes on a mountain ash tree branch right by a window of our house.
A few times it was accompanied by a male. About two weeks ago the
female returned with a fuzzy youngster. After three days with both
birds the youngster has come mostly alone. There have been numerous
skirmishes between it and other visitors to the holes, some with
wing-beating episodes, all always won by "Fuzzy." I've see it run off
the following to date: Ruby-throated Hummingbird, male Baltimore
Oriole (feathers actually flew as they beat on each other), Chickadee,
Phoebe, Kingbird, White Breasted Nuthatch, and Red Squirrel.
