Rinc-Dove.— These birds are exceedingly abundant in Cam- 
bridgeshire, where they do an incredible deal of mischief by de- 
vouring pease, beans and other leguminous plants. They are well 
known by their cooing notes which are heard incessantly from 
February to October: After that time they begin to collect 
together into enormous flocks, which disperse themselves over the 
country during the day-time to feed, but return regularly home in 
the evening to roost in their native woods and plantations. Some 
of these flocks do not wholly separate till very late in the spring, 
though the greater part pair off for the purpose of breeding by the 
beginning of March. In the Autumn I have observed that they 
subsist chiefly upon acorns and beech-mast.

Stockx-Dovr.—White, in his Natural History of Selborne, men- 
tions the Stock-Dove as being seen there during the winter months 
only, appearing in large flocks about the end of November, and 
departing in February. Whatever may be the case with respect 
to these birds in the southern counties, with us they certainly 
remain the whole year, as I have noticed them at all seasons and 
repeatedly found their nests. They are considerably less plentiful 
than the Ring-Dove, but have much the habits of that species with 
which they frequently associate in hard weather. Like them they 
breed very early in the spring. The nest which is flat and shallow, 
consists merely of a few sticks put loosely together in the hollow 
of some old tree. The eggs are two in number, white like those 
of the Ring-Dove, but somewhat smaller and rather more rounded. 
As far as I have observed, the Stock-Dove never cooes, but utters 
only a hollow rumbling note during the breeding season, which may
