It’s Not a Huge Deal if We Miss One Season of Climate Watch
Scientists have been dealing with fragmentary data for years and have many tools to deal with it.

Sitta pygmaea
Conservation status | Still common, numbers apparently stable. |
---|---|
Family | Nuthatches |
Habitat | Yellow pines, other pines, Douglas fir. Yellow pine (the commercial name for ponderosa and Jeffrey pines) is main habitat element throughout mountains of west; also occurs in Monterey pine on California coast. In some places extends into pinyon-juniper woodland and redwood canyons. On rare visits to lowlands, likely to be in planted conifers. |
Forages mainly on outermost and highest branches of pines, including cones and needle clusters; also on main branches and trunks. Sometimes sallies out to catch flying insects in the air. Often stores seeds in holes or crevices in bark.
Usually 6-8, rarely 4-9. White, lightly dotted with reddish-brown. Female incubates (15-16 days), is fed on nest by male and sometimes by additional helpers. Young: Are fed by both parents and often by helpers. Young leave the nest at about 20-22 days. 1 brood per year, occasionally 2.

Mostly insects and seeds. Diet in summer is primarily insects, especially beetles, wasps, caterpillars, and true bugs, also many others. In winter, also eats many seeds, especially pine seeds. Nestlings are fed mostly insects.
Nesting pairs often joined by 1-3 additional birds, usually their previous offspring, which help to defend the territory and raise the young; these helpers may roost in nest hole with the pair before the eggs hatch. Pairs with helpers tend to fledge more young than pairs without. Nest: Both sexes help excavate nest cavity in dead limb or snag, 8-60' above ground, usually higher than 20'. May tolerate some hole-nesting birds quite nearby (bluebirds, swallows) but not chickadees or other nuthatches. Nest in cavity is made of bark fibers, plant down, feathers. Pair usually roosts at night in nest cavity prior to egg-laying.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.

Also this month: Why are swirling flocks of starlings called murmurations? And how are nuthatches so good at tree climbing?
New Audubon report shows about half of Arizona’s birds are vulnerable.
