212 INSESSORES. CURRUCA. Pettychaps. 



Nest, &c. It builds its nest amongst nettles or other thick herbage, 

 forming it of the decayed stems oi goose-grass (Galium apa- 

 rine), or the seed-bearing stems of umbelliferous plants, 

 fibres of roots, and a little moss, flimsily interwoven ; lay- 

 ing four or five eggs, of a yellowish-grey colour, blotched 

 with wood brown, principally at the larger end. The alarm- 

 call of this species is very similar to that of the White-Throat 

 (Sylvia cinerea). In Bewick's early edition of his History 

 of British Birds, a mistake has been committed, in affixing 

 some of the synonyms of the Sylvia hippolais (Lesser Pet- 

 tychaps), to a bird evidently answering, by the description 

 there given, to the species now under consideration.
