THE DIPPERS AND WRENS 133 



House Wren {Troglodytes furvits) of Uruguay is 

 described by Mr. Aplin as sweet, " beginning with 

 a few grating notes, and then going off into a run 

 of remarkably sweet, full notes — the latter part 

 reminding one strongly of a good Warbler's song." 



Many of the North American Wrens, of which 

 one of the most familiar is the Winter Wren, are 

 celebrated for their cheerful and musical songs. 

 The Wrens are to a large extent migratory birds, 

 especially in the colder regions they inhabit. Even 

 our own well-known British species undertakes 

 migrations in some countries, and is a well-known 

 visitor on passage to Heligoland. The British 

 representatives of the present two groups of birds 

 are few in number. We have but one Dipper 

 indigenous, and two Wrens, one of these being 

 confined to the St. Kilda group of islands.
