From a few of these bundles may be extracted not only numbers of raptorial birds, large and small, including owls, but also the hawk-like cuckoo, the shrike, and even the swallow.
Another species of this group, the black cuckoo of India, apparently mimics the black drongo-shrike (Dicrurus ater), the resemblance between the two species being very close.
One of the most perfect cases of mimicry in birds is presented by a Madagascar thrush or babbler (Tylas eduardi), which resembles feather for feather a shrike (Xenopirostris polleni), from the same island.
The Tylas has departed from the normal coloration of its group to take on that of the shrike, a comparatively powerful and pugnacious bird.
Among gallinaceous birds besides the red-legged partridge, which is met with everywhere on the steppes, there are found also the Pterocles alchita and P. arenarius; and among the birds of other orders are the southern shrike (Lanius meridianalis), the Spanish sparrow (Passer cyaneus), and, the blue magpie (Cyano pica cooki).
