WIDE-SPREAD CUCKOO-PATTERN 197 



Malayan islands, which is indeed rather Pheasant- 

 like in shape, but Hawk-like in pattern. The 

 curious resemblance between most parasitic Cuckoos 

 and the Hawks in having long thigh-plumes must 

 be pure coincidence, as the short legs of the Cuckoos 

 are not suited for exhibiting this point, and besides, 

 the Hawks they most resemble are long on the 

 leg ; Hawks also sit erect, not horizontally like 

 Cuckoos. 



It must not be forgotten that the Sparrow-Hawk 

 pattern, or Cuckoo pattern, whichever one chooses 

 to call it, of a plain or nearly plain upper surface 

 and a barred lower side, is one of the most strikingly 

 recurrent patterns in the bird class, like the Magpie 

 pattern to which Mr. D. Dewar and myself have 

 drawn attention in our critical work on "The Making 

 of Species." It is found, for instance, among the 

 Passerines, in many of the thence-named Cuckoo- 

 Shrikes (Campephaga) ; in the male Barred Warbler 

 of Europe (Sylvia nisoria) ; in both sexes of a little 

 Australian Finch, the Cherry-crowned (Aidemosyne 

 modesta) ; in an Australian Duck, the Pink-eyed 

 (Malacorhynchus membranaceus) ; in the female 

 of the well-known Upland Goose (Chloephaga 

 magellanicd) — which also happens to have the 

 gamboge-yellow feet so common in birds of prey, 

 and so rare elsewhere," instead of the orange not 

 uncommon in waterfowl — and in both sexes of an 

 allied compatriot, the Ruddy-headed Goose (C. rubi- 

 diceps) ; in an Indian Owl (Glaucidium cuculoides), 

 and in some little Doves of the genus Geopelia.
