The birds, a male and a female, were shot in the neigh- 
bourhood of Dunbar, in the beginning of this month, and 
were sent by Mr Small, bird-stuffer, George Street. They 
are natives of the north of Africa, and of the south-eastern 
parts of Europe, and have been kept in a semi-domesticated 
state in various parts of England and Scotland. Several 
instances of single specimens of the bird, as well as small 
and even large flocks, apparently in a perfectly wild state, 
have, however, been observed in England at different times ; 
and it has now been admitted into the list of birds which 
occur as occasional visitors to Britain. In this instance, 
it is not improbable the birds may have escaped from 
the collection of some neighbouring proprietor. 
Dr Smith was informed by Mr Sanderson, George Street, 
that a flock of these birds, in a wild state, had this summer 
frequented Loch Leven, where it is possible they may have 
nested, and one of them had been sent to Mr Sanderson 
for preservation.
