this & similar species:
I observed an immature Yellow-bellied Sapsucker last year in the same valley as
this bird. (12th Documented Sighting of
a Utah Review Specie 19DEC2014).
I am quite familiar with Red-naped Sapsuckers, who are a common breeding bird in my area.I have observed and photographed RNSA for the past several years.
