Ornithological and Other Oddities 



in which a harmless insect-eating hawk (Har- 

 pagus diodon), inhabiting the neighbourhood of 

 Rio de Janeiro, is copied in that particular district 

 by a sparrow-hawk (Accipiter pileatus), which 

 there has a reddish-brown wing-lining like its 

 model's, but elsewhere a white one. This is a 

 good instance, and there are several equally- 

 striking ones. In Celebes one of the fierce 

 hawk- eagles {Spizdettis lanceolatus) exactly re- 

 sembles in both young and adult plumages the 

 harmless honey-buzzard (Perms celebensis) of 

 the same country. 



In India a small but fierce eagle (Hieraetus 

 pennatus) much resembles in size and colour 

 the lazy carrion - feeding pariah kite (Milvus 

 govinda), though it has not the forked tail of 

 that bird. 



Moreover, all round the world in warm 

 climates are found the hawks of the genus 

 Elanus, which, in their delicate grey plumage, 

 long narrow wings, and lazy flight, most re- 

 markably resemble gulls and terns. Mr. W. 

 H. Hudson, in his delightful book, " The 

 Naturalist in La Plata," mentions the resem- 

 blance of the Elanus to a gull, and says that 

 the birds seem less afraid of it than of other 

 hawks. And in India the species of Elanus 

 found there (£. cceruleus) is called by the natives 



"Jungle Tern"; I have seen it myself, and
