July or August, but I have not heard of its eggs being found in 

 or about Lahore. 



One species, namely Molpastes leucotis, the White-eared Bulbul, is, 

 so far as Lahore is concerned, a migrant. It appears in November and 

 leaves us in March. Hume writes of this species : — " In the cold 

 weather it may be met with at Agra, Oawnpore, and even Jhansi, 

 Sauofor and Hoshungabad : but during the summer months 1 know 

 only of its occurring in Cutoh, Kathiawar, Sind, Rajputana and the 

 Punjab. In all these localities it breeds, laying for the most part in 

 July and August in the Punjab, but somewhat earlier in Sind. I 

 have even in Rajputana seen eggs towards the end of May, but this 

 is the exception. Theobald states that this species breeds in the 

 neighbourhood of Pind Dadan Khan and Katas in the Salt Range. " 

 I am positive that no white-eared bulbul remains with us in Lahore 

 for the hot weather. Magrath says that it occurs in Kohat in the 

 summer, but is replaced by M. leucogenys in winter. It therefore 

 appears that this species undertakes a short double migration in a 

 easterly-westerly direction every year. 



Molpastes intermedins — the Punjab Red-vented Bulbul, on the 

 other hand does not appear to migrate ; it is common all the year 

 round in Lahore and I must have come upon scores of nests. It is 

 difficult to explain why one of these two species migrates while the 

 other does not. So far as I am aware their feeding habits are similar. 

 It is equally difficult to account for the migration of most of the 

 other species on which I have dwelt. In most cases we do not know 

 sufficient of the nature and extent of these migrations to formulate 

 any theory. The subject is one of some scientific interest and I hope 

 this note will have the effect of stimulating others to take up the 

 matter of these curious local migrations. 



In conclusion, I might say that the King-crow (Dicrurus ater) is 

 much more common in Lahore in summer than in winter. It comes 

 in great numbers to breed, but only a few individuals remain in 

 Lahore throughout the winter. It is quite possible that this species 

 is merely a summer visitor to some places in the Frontier Province. 

 I understand that the King-crows all leave Poona during the hot 

 weather.
