COSEWIC assessment and status report on the red crossbill percna subspecies, Loxia curvirostra percna, in Canada .: CW69-14/394-2016E-PDF
"This subspecies is a distinctive taxonomic group endemic to Canada. Previously known to breed only on the island of Newfoundland, it has within the past five years also been documented nesting on Anticosti Island. While the Canadian population is thought to be greater than was understood previously due to the recent discovery of a breeding population component on Anticosti Island, there is no evidence of an increasing trend. On the contrary, this taxon has experienced a substantial long-term decline. Further population decrease is expected based on identified threats, most notably competition and predation from introduced squirrels in Newfoundland, habitat loss due to logging, and a fungal disease affecting Red Pine"--Reason for designation, p. iii.
