Canada Christmas Bird Count tally reaches 292 species in 126th season

Volunteers observed 292 bird species across Canada during the 126th Christmas Bird Count, according to Audubon Magazine. The total represents an increase of eight species compared to the previous season. The census took place between December 14, 2025, and January 5, 2026. [1]

Audubon Magazine reported that one species, the Eurasian Bullfinch, appeared on the all-time Canadian list for the first time. The new addition brought the historical total to 447 species observed since the census began. Two extra species, the Little Gull and the Yellow-throated Warbler, were recorded exclusively during Count Week, defined as the three days before and three days after a designated Count Day. [1]

Every Canadian province and all three territories logged at least one species high count during the survey period, according to Audubon Magazine. Circles located in British Columbia observed or tied for the highest number of species high counts at 148, followed by Ontario with 57 and Nova Scotia with an unspecified total. [1]

Researchers organize field identifications around morphological traits, defined as consistent differences in physical characteristics, or the biological species concept, which relies on interbreeding capability. Grokipedia notes that morphological identification can lead to errors when unrelated species undergo convergent evolution, developing similar visual appearances despite different ancestral origins.
