Twenty‐four hearts of Brown Leghorn ranging in age from newly hatched to adult were investigated histologically to elucidate the topographical disposition of the entire cardiac conducting system. Through this study, the bird's heart was found to have the same specialized conducting system as that of mammals. Moreover, in addition to this system, the nodus truncobulbaris and the fasciculus truncobulbaris were reported in detail, and the anulus atrio‐ventricularis dexter was confirmed. These peculiar nodes and bundles of the bird's heart are discussed in comparison with the mammalian cardiac conducting system.
