Red Gallery – Northern Cardinal
The northern cardinal is a territorial song bird. The male sings in a loud, clear whistle from the top of a tree or another high location to defend his territory. He will chase off other males entering his territory. He may mistake his image on various reflective surfaces as an invading male, and will fight his reflection relentlessly. The northern cardinal learns its songs, and as a result the songs vary regionally. Mated pairs often travel together. Also, the songs of a northern cardinal will usually overlap more in syllables when compared to other northern cardinals near it than those far away from it.
