DARTFORD WARBLER 35 
cap is very nearly a resident species in England, 
some individuals remaining all the winter, while 
the Garden Warbler retreats further south. It is 
of the same size and general appearance as the 
Blackcap, but its upper parts are greenish-brown, 
rather than grey with a brownish tinge, and 
underneath it is also of a less clear shade of grey, 
while it altogether lacks the conspicuous black or red 
skull-cap. For a description of its nest and 
eggs, see under the preceding heading. It should, 
perhaps, be mentioned that the Garden Warbler's 
and Blackcap's eggs, together with the Robin's and 
Spotted Flycatcher's, are more subject to fading 
than those of almost any other species, and are 
sometimes hardly to be recognised if they have 
been blown for even a few weeks' time. 
DARTFORD WARBLER. 
(^Sylvia undata.) 
Furzy commons in the south of England are the 
haunts of this scarce and retiring little bird, which 
is, however, probably commoner in many districts 
than it is believed to be, owing to its making itself 
but little conspicuous either to eye or ear. It owes 
its English name to the fact that it was first dis- 
covered as a species near Dartford, in Kent, in the 
D 2
