February, but tarry longer in the cooler parts 

 of the country. Of the other migratory species 

 many individuals depart in March, but the 

 greater number remain on into April, when 

 they are caught up in the great migratory wave 

 that surges over the country. The destination 

 of the majority of these migrants is Tibet or 

 Siberia, but a few are satisfied with the cool 

 slopes of the Himalayas as a summer resort in 

 which to busy themselves with the sweet cares 

 of nesting. Examples of these more local 

 migrants are the grey-headed and the verditer 

 flycatchers, the Indian bush-chat and, to some 

 extent, the paradise flycatcher and the Indian 

 oriole. The case of the oriole is interesting. 

 All the Indian orioles (Oriolus kundoo) dis- 

 appear from the Punjab and the United 

 Provinces in winter. In the former province 

 no other oriole replaces O. kundoo, but in the 

 United Provinces the black-headed oriole 

 (0. melanocephalus) comes to take the place 

 of the other from October to March. When 

 this last returns to the United Provinces in 

 March the greater number of melanocephalus 

 individuals go east, a few only remaining in 

 the sub-Himalayan tracts of the province. 

 The Indian oriole is not the only species
