but after the spring moult the upper-parts are considerably 

 browner, the eye-stripe whiter and the under-parts whiter 

 and less marked with yellow than in Ph. t. trochilus. In- 

 dividuals vary, some having scarcely any green on the upper- 

 parts and no yellow on the under-parts. As summer advances 

 most become pale broAvn on the upper-parts with just a tinge 

 of green on the wings and rump. 



Juvenile. — Like that of Ph. t. trochilm. but rather less 

 yellow on the under-parts. 



First Winter. — Apparently less yellow on the under- 

 parts than first winter, and thus resembling adult winter. 

 Ph. t. trochilus. 



Greenish Warbler [Ph. n. viridanus). 



Adults. — Complete moult from August to October. In 

 March and April another complete moult takes place. The 

 sexes and the winter and summer plumages are alike. 



Juvenile. — Like the adult but considerably browner and 

 less green on the upper-parts. 



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

 times the innermost secondaries are moulted from August 

 to October, but not the rest of the wings nor the tail. 

 Plumage as adults. 



Wood- Warbler {Ph. s. .sibilatrix). 



Adults. — Complete moult from July to September. 

 From January to March another complete moult takes place. 

 The sexes are alike. The new spring plumage is like that of 

 winter but considerably' brighter, the upper-parts being 

 more golden-green and the 3'ellow of the chin and throat 

 brighter. As smnmer advances, abrasion makes the upper- 

 parts somewhat greyer-green and the throat becomes less 

 yellow. 



Juvenile. — Like the adult winter, but still duller green 

 with a grepsh-brown tinge on all the upj^er-parts 



First Winter. -The juvenile body-feathers are moulteil 

 in July and August, but apparently none of the wing-coverts 

 nor the wing- or tail-feathers. Plumage as the adult winter 

 but perhaps slightly more tinged with brown on the upper- 

 parts. 



First Summer. — Moult as in the adult after which the bird 

 is indistinguishable from the adult. 



Eversmann's Warbler {Ph. h. borealis). 



Adults. — Complete moult in August. From January to 

 March another complete moult takes place. The sexes and
