Population status

White-breasted Nuthatch
(Sitta carolinensis)

The White-breasted Nuthatch is well monitored in Canada by the Breeding Bird Survey (BBS), which covers about half of the breeding population; results indicate an increase in abundance of more than 200% since the early 1970s. BBS data from throughout North America also show a large increase at the continental level. The White-breasted Nuthatch is at an acceptable level relative to its national population goal (see BBS Canada graph below).
