552 PHYLLOSCOPUS NITIDUS, 



specimens collected at Futteghur and at Etawah. About the Sambhur Lake Mr. Adam says that it is very 

 rare; and it has only lately been added to the avifauna of Sindh, having been procured at Kotri by a collector 

 of Mr. Blanford's. But there is much more still to be learnt about the distribution of this tiny Warbler. The 

 extraordinary fact of a specimen of it having been shot in Heligoland some years since proves that it must 

 breed in Western Siberia. Many species, singularly enough, after breeding in Northern Asia stray, on their 

 migration back, westwards through Europe till they find their way to the little island of Heligoland ; and 

 this example of the Green Tree-Warbler must have been, as Mr. Seebohm infers, he. cit., a young bird which 

 had got out of its track. 



Habits. — This species frequents the upper branches of umbrageous trees, no matter whether they may 

 he situated in busy thoroughfares or in the quiet of the forest. It is especially fond of Jack-trees, which are 

 mostly found in the gardens of the natives, and again is very partial to the monarchs of the forest which 

 surround the many romantic tanks of the interior. In these spots its perpetual little chirrup invariably 

 discloses its presence when otherwise it would certainly be passed over in the lofty foliage which it frequents. 

 It affects the leaves of trees more than the next species, and darts out from its place of concealment on various 

 insects, after the manner of a Flycatcher. It is very lively in its actions, and is sociably inclined, for one 

 or two of its fellows may usually be found in an adjacent tree, each answering the other with its cheerful little 

 note. Its flight is swift, although its powers of locomotion are not much brought into play after it once 

 locates itself in its winter quarters ; it then merely darts from tree to tree, and often remains for a considerable 

 time without moving out of its retreat. The powers of wing which these little PhyUoscopi have are marvellous; 

 that they should be able to make their way across such a chain of mountains as the Himalayas, as some of 

 them undoubtedly d>>, is one of the greatest wonders connected with the migration of birds.
