THE COMMON ROOK. 181 



The rook entices its young from the breeding 

 trees, as soon as they can flutter to any other. 

 These young, for a few evenings after their flight, 

 will return with their parents, and roost where they 

 were bred ; but they soon quit their abode, and 

 remain absent the whole of the summer months. 

 As soon, however, as the heat of summer is sub- 

 dued, and the air of autumn felt, they return and 

 visit their forsaken habitations, and some few of 

 them even commence the repair of their shattered 

 nests ; but this meeting is very differently conducted 

 from that in the spring ; their voices have now a 

 mellowness approaching to musical, with little ad- 

 mixture of that harsh and noisy contention, so dis- 

 tracting at the former season, and seems more like a 

 grave consultation upon future procedure ; and as 

 winter approaches "they depart for some other place. 

 The object of this meeting is unknown ; nor are we 

 aware that any other bird revisits the nest it has

 again of their old nests ; but this is never, or only 

 occasionally, done by birds in a wild state. The 

 daw and rock pigeon will build in society with their

 situations as these birds require, the ruined castle, 

 abbey, or church tower, ledge in the rock, &c., are 

 not universally found, and are apparently occupied 

 from necessity. The rooks appear to associate from 

 preference to society, as trees are common every 

 where ; but what motive they can have in view in
