The Seychelles Blue Pigeon (also known as Seychelles Blue Fruit Dove) is a medium-sized pigeon which inhabits woodland areas of the granitic Seychelles archipelago.
It can be found either singly, in pairs or in small groups. Its diet consists mostly of seeds and fruit. Its nest is a flat platform made of sticks, with one or two eggs being present.
The pigeon is about 10 inches (25 cm) in length. Its head and breast are silver-grey, and these feathers can be raised when the bird is excited, giving it a ruffled look. Its wings, under-body and tail are dark blue. It has a distinctive bright crimson patch of orbital skin extending from forehead to crown. Its bill is dull yellow and it has dark grey legs.
