OF THE MIGRATION OF BRITISH BIRDS, 



Quam muUce glomerantur aves! uhi Jrigidus annus 

 Trans pontum fugat, et terris immittit apricis. 



Virgil. 



jLHE migration of birds, is a subject of so cu- 

 rious a nature, that every one who attempts to 

 •write the natural history of animals, ought to 

 look upon it as an essential part of his inquiries, 

 and at the same time should endeavour to assign 

 the cause why some birds prefer certain places for 

 their summer, others for their winter residence. 

 To be qualified for this task, it is necessary 

 that the inquirer should confine himself to 

 one certain tract the whole year; he should be 

 diligent in observing the arrival, and the disap- 

 pearance of birds ; he should commit every ob- 

 servation to paper, and compare them with the 

 remarks of correspondents, on the same subject.
