The pygmy nuthatch (Sitta pygmaea) is a tiny songbird, native to western North America. The pygmy nuthatch is 9–11 cm (3.5–4.3 in) long and with a wingspan of 19.7 cm (7.8 in), and weighs 9.3–11.4 g (0.33–0.40 oz). It ranges from southern British Columbia south through various discontinuous parts of the western U.S. (northwest U.S., Sierra Nevada range, southern Rockies, etc.), to central Mexico. It is usually found in pines (especially ponderosa pine), douglas-fir, and other conifers. Pygmy nuthatches clamber acrobatically in the foliage of these trees, feeding on insects and seeds; less often they creep along limbs or the trunk like bigger nuthatches.
Pygmy nuthatches nest in cavities in dead stubs of conifers, lining the bottom of the cavity with pine cone scales, plant fibers, and other soft plant and animal materials. They may fill cracks or crevices around the entrance with fur; the function of this behavior is unknown. The female lays 4–9 eggs, which are white with fine reddish-brown spotting. She does most of the incubation, which lasts about 16 days. The young leave the nest about 22 days after hatching.

Rare
Under 5% of wildlife watchers report a Pygmy Nuthatch sighting in Portland on a given day, based on 111 verified sightings from GBIF citizen-science data. It is the 182nd most-seen of the 230 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Pygmy Nuthatch in Portland on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Pygmy Nuthatch sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 6
Of the 6 cities where we can rate Pygmy Nuthatch sightings, Portland ranks 4th at under 5%. The best odds are in San Francisco (United States, about 20%), Minneapolis [Saint Paul] (United States, about 10%) and Denver (United States, under 5%).
Same genus: Sitta
The closest relatives of the Pygmy Nuthatch that you can see in Portland (genus Sitta, Nuthatches) are Red-breasted Nuthatch (about 40%) and White-breasted Nuthatch (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pygmy Nuthatch is recorded against all the birds logged in Portland (111 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.
