Population status

Northern Flicker
(Colaptes auratus)

The Breeding Bird Survey (BBS) provides monitoring information on the Northern Flicker, but does not cover the northern portion of the species' breeding range. BBS results indicate that the Canadian population has shown a small decrease, but of a magnitude considered to be within the category of little overall change since the early 1970s. However, regional declines are seen in the Prairie Potholes, Lower Great Lakes/St. Lawrence Plain, and Boreal Hardwood Transition Bird Conservation Regions (BCRs; all BCRs with reasonably reliable results are displayed below). At the continental level, BBS results from throughout North America indicate an almost 40% decrease in abundance since the early 1970s. The Northern Flicker is currently considered to be at an acceptable level relative to its national population goal, but has dipped below in the recent past (see BBS Canada graph below).
