The Breeding Bird Survey (BBS) provides good coverage of the range of Ring-necked Pheasant in Canada, and is the best source of monitoring data. BBS results indicate that the population has changed little overall since about 1970. At the regional level, trends among the Bird Conservation Regions (BCR) in which the species occurs vary; numbers are increasing in the Atlantic Northern Forest BCR, and decreasing in the Lower Great Lakes / St. Lawrence Plain and the western BCRs. However, the Prairie Potholes BCR indicates an more or less unchanged population. The Christmas Bird Count provides population data during the winter and, in contrast to the BBS, suggests a large decrease in the Canadian population since the early 1970s. However, variation in stocking and hunting rates during the fall and early winter may affect the Christmas Bird Count results. BBS trends measure the population in the spring, after the effects of winter mortality and when the influences of stocking and hunting rates on the population trend are reduced. The BBS results are used here to determine that there has been little overall change in the population since 1970, this assessment is considered to be of medium reliability.
