The Red Crossbill is found throughout the world's boreal and coniferous forests, and is a common species in parts of Canada's mature coniferous forests. The species is nomadic and opportunistic and may breed in any season (late December to mid-October) when food supply is adequate (Adkisson 1996). While population declines have been dramatic in Newfoundland and Labrador, results of the Breeding Bird Survey and Christmas Bird Count suggest that the species' population has shown a moderate increase in Canada as a whole since the early 1970s. This assessment is considered to be of medium reliability due to the difficulty in adequately surveying such a nomadic species. There are presently 10 recognized Red Crossbill types across North America. One type (Type 8), known as the percna subspecies, is endemic to insular Newfoundland, though it was recently found on Anticosti Island, Quebec (Tremblay et al. 2018). This subspecies was designated as Endangered by the Committee on the Status of Endangered Wildlife in Canada because of its declining population (COSEWIC 2004a), and was listed as such under the Species at Risk Act in 2005. COSEWIC recently reassessed percna as Threatened, based on the discovery of this new breeding population in Quebec (COSEWIC 2016b). This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.
Although still common in much of their range, the species' numbers fluctuate markedly, depending on food availability. Forest fragmentation and reductions in mature forest associated with forestry practices have caused decreases in some areas (Adkisson 1996). In the west, extensive loss of pine trees throughout British Columbia's interior, and now Alberta's jack/lodgepole pine hybrids, from an unprecedented epidemic of mountain pine beetle (Federal, Provincial and Territorial Governments of 2010), will likely influence the abundance and distribution of crossbills in future. The large decline in the percna subspecies during the latter part of the 20th century are likely due to the loss of large-coned white and red pine as a result of insect outbreaks and forest harvesting, as well as the introduction of red squirrels who compete for the same cone resource (COSEWIC 2016b). Other probable threats include fire and fire suppression, roadways, and mining (COSEWIC 2016b).

Environment and Climate Change Canada and partners have developed Bird Conservation Region Strategies in each of Canada’s Bird Conservation Regions (BCRs). In these strategies, selected species are identified as priorities for one or more of the following reasons:
