Population status

Red-bellied Woodpecker
(Melanerpes carolinus)

The Breeding Bird Survey (BBS) covers the small breeding population of Red-bellied Woodpeckers that is found in southern Ontario. Despite only moderate precision, BBS results clearly demonstrate that the population has shown a large, almost exponential increase in Canada since about 1970. The North American results of the BBS also indicate that the continental population has increased since the 1970s, but at a steadier, more moderate pace than the Canadian population. The Red-bellied Woodpecker is at an acceptable level relative to its national population goal (see BBS Canada graph below).
