 gilegus) is a permanent resident of Kashmir and the 

 North- Western Himalayas, but in mid-winter many 

 individuals are driven by the cold into the Frontier

 Lahore, where they consort with the crows. If the 

 winter is a severe one large numbers of rooks come to 

 Lahore, otherwise these birds are not very numerous. 

 The same applies to the jackdaw [Corvus monedula), 

 but he never comes in such numbers as the rook. There 

 is in the octagonal bird house in the Lahore ** Zoo " 

 a compartment in which there is a " Happy Family " 

 of ravens, rooks, and jackdaws, with an Australian 

 crow-shrike and a Nicobar pigeon to keep them 

 company. Thus every one who cannot already do 

 so may learn to identify the various Corvi which visit 

 Lahore in the winter.
