The red-naped sapsucker (Sphyrapicus nuchalis) is a medium-sized North American woodpecker. Long thought to be a subspecies of the yellow-bellied sapsucker, it is now known to be a distinct species. The red-naped sapsucker is one of four North American woodpeckers in the genus Sphyrapicus. It has no subspecies. First described by Spencer Fullerton Baird in 1858, it was initially thought to be a subspecies of the yellow-bellied sapsucker. However, there are significant genetic differences between this species and the yellow-bellied sapsucker, and the American Ornithologists' Union recognized it as a distinct species in the seventh edition of its North American birds checklist, published in 1998. Genetic analysis has shown that the red-naped sapsucker is a sister species with (and very closely related to) the red-breasted sapsucker, and that these two species form a superspecies with the yellow-bellied sapsucker. All three species are known to hybridize with each other, with hybrids between red-naped and red-breasted sapsuckers proving particularly common.
The genus name Sphyrapicus is a combination of the Greek words sphura, meaning "hammer" and pikos, meaning "woodpecker... Wikipedia →

Rare
Under 5% of wildlife watchers report a Red-naped Sapsucker sighting in Torreón on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 75th most-seen of the 86 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
October
In that month about 10% of wildlife watchers report a Red-naped Sapsucker in Torreón on a given day, against under 5% in November to September, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Red-naped Sapsucker sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 14 cities where we can rate Red-naped Sapsucker sightings, Torreón ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Dallas (United States, under 5%) and Salt Lake City (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Red-naped Sapsucker is recorded against all the birds logged in Torreón (6 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
