Dietary Habits

The northern cardinals belong to the mainly seed eating bird category due to their characteristic strong beak, they mostly go searching for food during dawn and dusk. They can also eat insects and sometimes fruits also. They used to burrow in the bushes of trees and dig out insects and eat them.


Habitat

The members of the Cardinalidae Family like better to live in deep forests and tend to build their nests on the thick and dense bushes of trees. Cardinals are usually endemic to the USA. Most North American cardinal species migrate south for the winter, whether further south within the continent or extending into the neotropics.


Breeding and Reproduction

Most species of Cardinals or monogamous means they breed only during breeding season. The breeding season is in sync with the abundance of insects. Most species build open-cup nests made from grasses and twigs depending on the species. These nests would be within the trees, often high in the crown. The nest building is completed by both partners or by the female alone. The male and feminine take turns incubating the nest, often the male would feed the feminine.
