The Red-naped sapsucker prefers to nest in almost any kind of tree but prefers riparian trees bordering forest.
The Red-naped sapsucker has a very varied diet. This includes various insects, sap, cambium, and fruits. Sap is acquired by drilling sap wells lots of little holes that the tree bleed sap out of. The sap sucker eats this sap as well as the insects that are attracted to it.
This species of sapsucker uses a wide variety of trees and is not too closely linked to one species and therefor is not as sensitive to habitat availability.
In California the Red-naped sapsucker inhabits more arid climates. In the summer it prefers riparian and coniferous forest habitats.
The Red-naped sapsucker moves into the warmer desert riparian areas of California during the winter.
