Habitat
The dense mixed and conifer forests typical of western Washington are the preferred breeding habitat of Red-breasted Sapsuckers. They are often found in mature and old-growth forests, but will breed in second growth as long as there are some large nesting trees. They can also be found in riparian habitats with large cottonwoods.
Behavior
Sapsuckers get their name from their foraging strategy, which consists of drilling neat horizontal rows of holes into tree trunks and then returning to those holes later to feed on the running sap and the insects attracted to it. Unlike most woodpeckers, they forage in healthy trees and can actually kill a tree if they drill too many sap-holes around its trunk, although this is quite uncommon.
