Like mammals, avians (birds, or members of the class Aves) have four-chambered hearts, consisting of two atria and two ventricles. By contrast, reptiles and amphibians have three-chambered hearts (two atria and one ventricle, sometimes with an incomplete septum in reptiles) and fish have two chambers (one atrium and one ventricle).
