Red-breasted Sapsucker (Sphyrapicus ruber) is divided into two subspecies,
a northern one, S.r.ruber, and a southern one, S.r.daggetti [sic ; Peterson
has a spelling error].
S.r.daggetti has more white on the back, much like Red-naped Sapsucker, and
little or no yellow on the belly.
All sapsuckers have white wing patches but they often just show a white line
on the closed wing.
Cf. - NGS Field Guide, p.269
- Audubon Master Guide (Vol 2) has a photograph on p.231 which shows a
Red-br.Saps. with very little white on the wing and no yellow on the
belly.
- Kenn Kaufman's Field Guide to Advanced Birding.
Peterson's Field Guide may be the granddaddy of them all but is no longer the
last word in bird identification.
On a recent trip to California I saw a sapsucker with a head which was mostly
red but with clear black markings in a pattern suggesting that of Red-naped or
Yellow-bellied. Must have been a hybrid. According to Kaufman, the three
species hybridize frequently and the offspring may look like anything.
