of a public road, and will place its nest in a stunted bush about 
a foot from the ground. On one occasion we found a nest in 
a shrubbery, at Avington Park, built in among the growers of 
an elm tree among the dead leaves and rubbish, at a height of 
quite four feet from the ground. The nest was shaped like 
that of a Uren, and opened outwards, but was built of the 
usual rough grass of the Chiffchaff’s nest. That there should 
be no mistake about the species to which the nest belonged 
we caught the hen-biid in a butterfly-net, as she quitted^the 
nest, and the skin is in the British Museum at Inis day, for, on 
finding that the eggs were just hatching out and could not he 
flown, we sought to let the little captive go, but found that she 
had died ol fright in the net, and we were, therefore, obliged 
to make a specimen of her for the Museum. 
Eggs.— From five to seven in number. Ground-colour 
china-white or creamy-white. As with the Willow- Wren there 
are two distinct types of eggs, one with numerous small dots, 
and one with more scattered but larger spots and blotches. The 
spots are deep chocolate or reddish-brown, or more' often 
purplish-brown, almost black Underlying spots of violet-grev 
are seen in many eggs, but there is seldom an indication of a 
ring round the larger end. Axis, o'6-o'6 5 inch : diarn o' 4 c- 
0-5.
