There are two types of cardinals that can be found in North America, one is the Northern Cardinal. This cardinal is slowly moving and nesting farther North every year. It is thought that the use of birdfeeders has caused this.
The other is the Red-crested Cardinal, also known as the Brazillian Cardinal. This bird type is an exotic and can be seen in Florida and California. In most cases it is because it may have escaped from captivity.
Cardinals have large bills and are part of the same family as grosbeaks. These birds use their strong bills for eating seeds. They can be located through their loud singing usually from treetops.
