Cetti's Warbler (Cettia c. cetti). 



Adults. — Complete moult in late summer. In March 

 the body-feathers, lesser and median wing-coverts, inner 

 greater coverts and the innermost secondaries are moulted, 

 at all events in some individuals, though others seem not 

 to moult at all in the spring. The sexes and the winter and 

 summer plumages are alike. 



Juvenile. — Like the adults but slightly less chestnut on 

 the upper-parts and the white of the under-parts rather 

 duller 



First Winter.— The juvenile body-feathers and wing- 

 coverts are moulted in July and August but not the primary- 

 coverts, wing- or tail-feathers. After the moult the bird 

 becomes like the adult. 



MousTACHED Warbler {Luscmiola m. melanopogon) . 



Adults. — C'Omplete moult in early autumn. In February 

 and March the body-feathers are moulted, but not the \^ings 

 nor the tail-feathers. The sexes and winter and summer 

 plumages are alike. Abra.sion gradually makes the crown 

 more uniform black, the mantle more clearly streaked and 

 the under-parts whiter. 



Juvenile. — Like the adults, but the upper-parts more 

 tawny and less chestnut. 



First Winter. — The juvenile body-feathers are moulted 

 from June to August, but not the wing- or tail-feathers. 

 After the moult the bird becomes like the adult.
