252 Observations on three British Species of Warblers. 
Some German writers call this bird Griiner Sanger; and Beck- 
stein has called it Lamlrolchen and Laubvolchen. 
This bird is apparently figured in Nillson’s Ornithologia Sue- 
cica, vol. i. Au 
Description.— Length about five inches: bill dusky; irides 
hazel. The upper part of the head, back, scapulars and coverts 
are dusky yellowish green. Over each eye there is a bright brim- 
stone-coloured streak, The cheeks, throat and breast are yellow, 
palest on the breast. and inclining to white ; the lower part of 
the breast, belly and under-tail coverts white. 
The plumage of the female is like that of the male; bnt she 
appears somewhat larger, and weighs three drachms. 
This bird has been confounded with the species next described 
(S. Trochilus). But it may be easily distinguished by its colour 
and habit. The upper parts are of a brighter greenish colour ; 
and it is found in more wooded situations than the Sylvia Tro- 
chilus.., 
This species is migrative like the other two: it arrives very 
early in May, and departs in September.

This is the Yellow Wren of Edwards; the Middle Willow 
Wren of White in Hist. Selborne; the Scofch Wren of Pennant 
and Latham; and the Willow Wren of Bewick. 
The provincial names for it are Ground Wren, or Ground 
Huckmuck. 
This bird weighs two drachms and almost three quarters, and is 
five inches in length, being somewhat smaller than the last. It 
is to be distinguished from that bird by the upper parts of the 
plumage being more of a greenish yellow olive, the under parts 
being whitish tinged with yellow ; quills dusky edged with yellow; — 
over the eye a yellow line; legs light brown: eggs spotted with 
dark rust colour. This species is more frequently found about 
willows and osiers than the other two are. )
