The yellow-bellied sapsucker (Sphyrapicus varius) is a medium-sized woodpecker that breeds in Canada and the northeastern United States. The yellow-bellied sapsucker was described and illustrated using a hand-coloured plate by the English naturalist Mark Catesby in his The Natural History of Carolina, Florida and the Bahama Islands which was published between 1729 and 1732. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he included the yellow-bellied sapsucker, coined the binomial name Picus varius and cited Catesby's book. The specific epithet varius is the Latin word meaning "various", "diverse" or "variegated". Linnaeus specified the type locality as America septentrionalis (North America) but the locality is now restricted to South Carolina. The yellow-bellied sapsucker is now placed in the genus Sphyrapicus that was erected in 1858 by the American naturalist Spencer Baird with the yellow-bellied sapsucker as the type species. Within the genus Sphyrapicus, the yellow-bellied sapsucker is sister to a clade containing the red-breasted sapsucker (Sphyrapicus ruber) and the red-naped sapsucker (Sphyrapicus nuchalis...

With luck
About 10% of wildlife watchers report a Yellow-bellied Sapsucker sighting in Reserva de la Biosfera Mariposa Monarca on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 83rd most-seen of the 103 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February and November–December
In those months about 10% of wildlife watchers report a Yellow-bellied Sapsucker in Reserva de la Biosfera Mariposa Monarca on a given day, against under 5% in January, March, May and October, the lowest months. Those are among Reserva de la Biosfera Mariposa Monarca's driest months, with about 30 mm of rain a month against 270 mm in July. April and June–September have too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Yellow-bellied Sapsucker sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
16th of 44
Of the 44 parks where we can rate Yellow-bellied Sapsucker sightings, Reserva de la Biosfera Mariposa Monarca ranks 16th at about 10%. The best odds are in Riding Mountain National Park (Canada, about 40%), Congaree National Park (United States, about 30%) and Elk Island National Park (Canada, about 20%).
Same family: Picidae
The closest relatives of the Yellow-bellied Sapsucker that you can see in Reserva de la Biosfera Mariposa Monarca (family Picidae, Woodpeckers) are Acorn Woodpecker (about 10%) and Hairy Woodpecker (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow-bellied Sapsucker is recorded against all the birds logged in Reserva de la Biosfera Mariposa Monarca (11 verified sightings from 2019 to 2026), 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.
