are birds of prey, and having at all times in this 

 island means of living, are not obliged to quit 

 their quarters. 



Shrikes. The Flusher, or red back Shrike, and the 

 great Shrike, breed with us ; we have not heard 

 of the other, so suspect that it migrates. 



Ckows. Of this genus, the Hooded Crow migrates re- 



gularly with the Woodcock. It inhabits North 

 Britain the whole year : a few ai'e said annually

 also in Sweden and Austria, in some of the 

 Swedish provinces it only shifts its quarters, in 

 others it resides throughout the year. I am at 

 a loss for the summer retreat of those which 

 visit us in such numbers in winter, and quit our 

 country in the spring; and for the reason why a 

 ' . bird, whose food is such that it may be found at 

 all seasons in this country, should leave us.

Visitants. Ed. 

 Cuckoo. Disappears early in autumn; the retreat of 

 this and the following bird is quite unknown 

 to us. 



Wryneck. Is a bird that leavcs us in the winter, and re- 

 visits us in the spring a little earlier than the 

 Cuckoo. If its diet be ants alone, as several 

 assert, the cause of its migration is very evident.
