Example text

27 The accounts from New Zealand suggest that the magpie may once have filled a niche closer to a bird of prey and that specific ecological pressures within Australia (perhaps absent or diminished in New Zealand) have resulted in the magpie largely abandoning vertebrate and live bird prey in preference for smaller insectivorous fare. The digits of the magpie’s foot, particularly the apposable, backward facing digit is more reminiscent of the structure of a bird of prey than of a songbird. Clearly, foot construction can also be a sign of fighting and, to some extent, this applies to magpies as well.

Magpies, by contrast, stay on the ground for feeding and take to trees only for roosting and breeding. The only above-ground feeding by magpies occurs during breeding time when nestlings are being fed. As soon as 24 Australian Magpie magpie nestlings fledge, they too are brought to the ground and walk with a parent during foraging bouts. Magpies, currawongs, butcherbirds and woodswallows tolerate each other well within a given terrain, but usually by observing a foraging hierarchy. Magpies assume absolute first feeding rights on the ground.

Paeleoanthropologists look at leg bones of extinct animals with great interest because the legs and the way of their articulation with the hip can tell them something about the locomotion of a species. A long thigh bone (nearly or of equal length as the lower leg bone), for instance, indicates that the animal in question was a fast runner. A short thigh bone, by contrast, generally indicates that the species is predominantly a walker. In magpies, the femur is substantially shorter than the tibiotarsus, giving a clear indication that the bird is not designed for habitual running but for walking.
