The northern cardinal is found in residential areas throughout its range. Bird feeders attract it by using feeders containing seeds, particularly sunflower seeds and safflower seeds. An increase in backyard feeding by humans has increased the range of this species, with an estimated global range of 5,800,000 km2 (2,200,000 sq mi) and a global population of some 100 million.[1] Populations appear to remain stable or increasing.
