Primarily a species of the eastern and southern United States, the Northern Cardinal reaches Canada mainly in Ontario's Carolinian region but has expanded to eastern Ontario, southern Quebec and parts of New Brunswick and Nova Scotia. Results from the Breeding Bird Survey show that populations have increased greatly since 1970 and continue to increase in both number and breeding range. These increases are probably the result of bird feeding and warmer winters (McLaren 2007).
The Northern Cardinal has benefited from changes brought to the landscape since the settlement period in North America. With the conversion of forests to agriculture and suburban areas, nesting habitat has increased and bird feeding operations have ensured an adequate supply of food in areas that would otherwise have not been suitable (Halkin and Linville 1999, Erskine 1992). Winter temperatures have also warmed. Despite its obvious success, the Northern Cardinal is a frequent host of Brown-headed Cowbird parasitism; nesting success is generally low (Halkin and Linville 1999).
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:
