The Greenish Willow-Warbler. 
THE GREENISH 
WILLOW-WARBLER. 
( Phylloscopus viridanus.) 
nest is placed close to the ground, 
and is composed of dry grass, some- 
times half-domed, and is lined with 
feathers. Occasionally the nest is 
to be found at a height of some 
few feet from the ground. The 
eggs are from five to seven in 
number, white, with well-marked 
spots of chocolate or reddish-brown, 
inclining to purplish-brown or 
black, with underlying spots of 
violet-grey. 
This species has only once been obtained in Great 
Britain, a single individual having been shot on the 
Lincolnshire coast by Mr. G. H. Caton Haigh, on the 
5th of September, 1896. It is an Asiatic species, breeding 
in the mountains of Central Asia and the Himalayas, and also in Europe in North 
East Russia and the Ural Mountains. It has been noticed on three occasions in 
Heligoland, and so there is nothing very surprising in its occasional wandering to 
Great Britain. 
In appearance the species is very like our Willow-Warbler, but is greener on the 
upper surface and is distinguished by the yellowish-white tips to the greater wing- 
coverts, which form a distinct wing-bar. The under parts are pale greenish-yellow, 
with the axillaries and under wing-coverts pale yellow. In its breeding home this 
little Warbler is said to frequent willow-bushes and the tall steppe-grass. By some 
observers its song has been recorded as feeble, but by others it is stated to have a 
very powerful song. The nest is placed on the ground and 
is domed, but the eggs are as yet unknown. 
Although a frequent visitor to 
the island of Heligoland, this 
small Warbler is of rare occur- 
rence in Great Britain, where less 
than a dozen specimens have hitherto been recorded, though 
it has been met with in different parts of the United King- 
dom. It nests throughout Siberia, and its winter home is 
in China, Borneo and India. 
It is a tiny species, scarcely larger than a Gold-crest, 
olive green in colour, with an indistinct line of yellow down 
the centre of the crown, and shewing a double wing-band 
of yellow, caused by the yellow tips to the median and
