Range extension of the threatened Red Crossbill (Loxia curvirostra percna) in Canada: new insights from Anticosti Island, Québec

A significant range extension for the threatened Red Crossbill (Loxia curvirostra percna) has been identified on Anticosti Island, Québec, Canada. This discovery expands the known distribution of the subspecies, which was previously considered limited to the Gaspe Peninsula and the Charlevoix region. Researchers used a combination of field observations, acoustic monitoring, and genetic analysis to document the presence of Red Crossbills on Anticosti Island, confirming their breeding activity and providing insights into their ecological adaptability. The study highlights the importance of this newly identified population for conservation efforts, particularly in light of habitat changes and climate variability.
