6). In songbirds, the three forward digits are usually placed rather close together while those of raptors are spaced widely apart. All digits are freely mobile (which is not the case in the kookaburra where the third and fourth digit are partly fused at the lower end, called a syndactyl foot), and the digit facing backwards is freely apposable. This is a hallmark of perching birds. In birds of prey, the same digit is also freely apposable. 3, next chapter). The difference between the toes of perching birds and birds of prey lies largely in the padding at the underside of the digit and in the length and shape of each claw.
This method of locomotion in magpies is consistent with their feeding behaviour. Ground feeders, including shorebirds and waders, are bipedal. All other artamids that are not exclusively or predominantly ground feeders have Anatomy 21 obviously had no need to develop the anatomical features necessary to achieve a bipedal gait. It is useful to remember that birds were bipedal long before primates became bipedal. Feet There are about seven types of feet in birds. One distinguishing characteristic is whether the feet are fully or partially webbed or not; another is the number and arrangement of the digits (toes).
Group size increases as a result of breeding and then declines prior to the next breeding season. The degree of the decline depends on several factors including attrition rate of the young and group behaviour towards juveniles. In Queensland, it appears that juveniles regularly disperse towards the end of the previous breeding season16 while in Canberra17 and those in Western Australia18 the young are often permitted to remain within the natal group and they do so often for as many as three years.
