* A bird intermediate between the Mallard and Wigeon has been 
procured by Pincombe of Devonport ; the brilliant wing spot 
being very distinct. It is rather astonishing how prone some 
animals are to unnatural alliances even when surrounding cir¬ 
cumstances are but a degree removed from a state of nature. 
Montagu relates that in a pond appropriated to wild fowl, Widgeons 
have been known to form matrimonial connexions with the Pin¬ 
tail, although there was no lack of other Widgeons of both sexes 
in the same pond.
