  • Buff white cheeks, chin, and belly

Similar Species

Similar to Pygmy Nuthatch, which would be very tricky to distinguish, except that the two species never meet, being very sedentary and separated by a roughly 750 km gap in Texas where neither occurs.

Distribution

Southeastern United States and the Bahamas, on Grand Bahama. Found from south-eastern Oklahoma and eastern Texas through central Arkansas, Tennessee, and the Gulf Coast states, to southern Maryland and Delaware, Virginia, then south to southern Florida.

Taxonomy

Closely related to Pygmy Nuthatch, with which it has sometimes been considered conspecific in the past[2].

Subspecies

There are two subspecies[1]:

  • S. p. pusilla:
  • Pine forests of south-eastern US
  • S. p. insularis:
  • Grand Bahama Island

Habitat

Mixed forests, primarily pine, and gardens.

Behaviour

Diet

The diet includes cockroaches, beetles, and spiders in summer, and pine seeds in winter. Often visits garden feeders.

Breeding

They nest in a tree cavity; the eggs are incubated for 14 days. The young fledge 18 days later.
