Vocal Bird anatomy: Birds produce sounds through the air that passes through the Syrinx, which is shown close up in the bottom right. In order for birds to produce sound, they use an organ located above the lungs called the syrinx , which is composed of tracheal rings, syringeal muscles, Tympaniform membrane, and internal bony structures that ...
Male birds have two Z chromosomes (ZZ), and female birds have a W chromosome and a Z chromosome (WZ). [77] A complex system of disassortative mating with two morphs is involved in the white-throated sparrow Zonotrichia albicollis , where white- and tan-browed morphs of opposite sex pair, making it appear as if four sexes were involved since any ...

Birds (class Aves) – winged, bipedal, endothermic (warm-blooded), egg-laying, vertebrate animals. There are around 10,000 living species, making them the most varied of tetrapod vertebrates. They inhabit ecosystems across the globe, from the Arctic, to the Antarctic.
Most birds have four toes, typically three facing forward and one pointing backward. [7] [10] [8] In a typical perching bird, they consist respectively of 3, 4, 5 and 2 phalanges. [2] Some birds, like the sanderling, have only the forward-facing toes; these are called tridactyl feet while the ostrich have only two toes (didactyl feet).
In bird anatomy, the gape is the interior of the open mouth of a bird, and the gape flange is the region where the two mandibles join together at the base of the beak. [33] The width of the gape can be a factor in the choice of food. [34] The gape flange on this juvenile house sparrow is the yellowish region at the base of the beak.
