Range extension of the threatened Red Crossbill (Loxia curvirostra percna) in Canada: new insights from Anticosti Island, Québec
Red Crossbill (Loxia curvirostra percna; e.g., Type 8) is considered a distinctive taxonomic group likely restricted to the island of Newfoundland. Although it has been speculated that the percna subspecies may be extinct, recent works continue to show that Red Crossbills from insular Newfoundland a...
