Summary

Our bird of interest is the Northern Cardinal, Cardinalis cardinalis.

This species is widespread across the eastern and southern US. It’s so well-known and loved that it’s the state bird for 7 states.

Northern Cardinals are among the most abundant birds in North America. They’re familiar denizens of backyards that visit feeders all year long. So it shouldn’t be surprising to hear that ornithologists have done a lot of research on this abundant and conspicuous species.
