The Pyrrhuloxia - also called the Desert Cardinal - is closely related to the Northern Cardinal and can look confusingly similar, especially the females. Both belong to the family Cardinalidae, but they differ in colour, bill shape, and habitat.

The easiest way to tell a Pyrrhuloxia from a cardinal is the bill. The Pyrrhuloxia has a thick, curved, parrot-like yellow bill, while the cardinal has a straight, conical orange-red bill. If you see a “cardinal” in the desert Southwest with a yellow bill, it is a Pyrrhuloxia.
