The remaining fourteen bones are the phalanges, three to each digit excepting the great toe; h, distal phalanx of the hallux or great toe." -Whitney, 1911

"Fig 34 - Bones of a bird's hind limb: from a duck, Clangula islandica. A, hip: B, knee: C, heel or ankle-joint; D, bases of toes. A to B, thigh or "second joint"; B to C, crus, leg proper, "drumstick," often wrongly called "thigh"; C to D, metatarsus, foot proper, corresponding to instep, or foot from ankle to bases of toes; in descriptive ornithology the tarsus; often called "shank" From D outward are the toes or digits. fm. femur; tb, tibia, principal (inner) bone of leg; fi, fibula, lesser (outer) bone of leg; mt, principal metatarsal bone, consisting chiefly of three fused metatarsal bones; am, accessory metatarsal, bearing 1t, first or hind toe, with two joints; 2t second toe, with three joints; 3t, third toe, with four joints; 4t, fourth toe, with five joints. At C there are in the embryo some small tarsal bones, not shown in the figure, uniting in part with the tibia, which is therefore a tibio-tarsus, in part with the metatarsus, which is therefore a tarso-metatarsus; the ankle-joint being therefore between two rows of tarsal bones, not, as it appears to be, directly between tibia and metatarsus."
