Red-naped Sapsucker - Spyyrapicus nuchalis

Sapsuckers are well-named, as they are famous for their behavior of drilling a series of holes in the bark of a tree and later returning to the oozing holes to drink the sap or catch insects there. Before the 1980's there were only 2 birds in the Sapsucker genus, Sphyrapicus, The Yellow-bellied Sapsucker and Williamson's Sapsucker. In the mid-1980's the Yellow-breasted Sapsucker, S. varius, was split into 3 species. The Pacific Coast group of birds, the reddest, were separated out as the Red-breasted Sapsucker, S. ruber, and the Rocky Mountain group was given the name Red-naped Sapsucker, S nuchalis , a species we don't often see along the west coast. 

The Red-naped is quite similar to the Yellow-breasted Sapsucker found across the lower U.S. from Texas over to the east coast. The most significant difference is a red patch on the back of the neck, the nuchal area or "nape". The males of both species have a red throat with a black border, although the black border on the Red-naped is thinner.


First photo shows the red throat with the thin black border, and just a hint of red on the nape. 

Second photo and third photos are crops to show a bit more of the red nape. We can also see a bit of the yellow wash on the shoulder and belly.


Fourth photo show the yellow wash best, and the last photo gives us a look from below, showing the broad black chest band and the extensive red in the throat, and looking like a giant hummingbird. A female Red-naped Sapsucker would look much the same as this male, but she would have a white in the area of the chin, just about the red neck.




For those wishing to read more, especially about the rare occurrence of a female Red-naped with a totally red throat, see this article:

Photos were taken looking up at quite an angle, so it's hard to show the pattern on the back and the nape. It was also quite a challenge to compose a shot, as the bird stayed only briefly at each visit.
