126 BIRDS OF SOMERSETSHIRE. 
passes over the nape; back, scapulars and tail- 
coverts olive-green; lesser wing-coverts blue, in- 
clining to dusky in the centre of each feather; 
ereater wing-coverts the same, but tipped with 
white; quills dusky, narrowly margined with blue 
and white; tertials dusky, tinged with blue, mar- 
gined with olive-green and tipped with dull white ; 
tail dusky, much tinged with pale blue, the outer 
feather on each side white; breast, belly and all the 
under parts sulphur-yellow; legs, toes and claws 
bluish black. 
The egg of the Blue Tit is much like that of the 
Great Tit, only smaller in size. 
Coxe Tit, Parus ater. The Cole Tit is not quite 
so common as the last species, though in this neigh- 
bourhood more so than the Great Tit. It is resident 
here throughout the year, and much resembles the 
other Tits in habits, manners and food, and is to be 
constantly seen with them. Like the others, its food 
consists principally of insects and buds: kernels of 
the stones of fruit also form part of its food, and 
I have often seen the bird hammering at the shells 
with its beak to break them. 
A short time ago I observed a Cole Tit busily 
engaged in picking some of the white, mildew- 
looking substance on an apple tree: I brought 
some of the mildew in, examined it with a micro- 
scope, and found it full of small insects, which the 
bird must have been eagerly devouring. Montagu,
