Trends

Trends

BBS results for this species in the NWT, data suggest species popualtion is declining however the magnitude of that decline is largely unknown. but could be upwards of 50%. Data have low reliability and should be interpreted with caution (Environment Canada, 2014. North American Breeding Bird Survey - Canadian Trends Website, Data-version 2012. Environment Canada, Gatineau, Quebec, K1A 0H3). BBS results for this species in the NWT, data suggest population is declining however the magnitude of that decline is largely unknown.Data have low reliability and should be interpreted with caution
