A beautiful pigeon sized bird. Unusual with its thin black crest. Close up, in sunlight, the dark feathers on the back have a iridescence from green through purple. Unmistakeable in flight with the broad flat wing tips.Their main food source is insects and worms. They are found in arable fields or coastlines (particularly in winter when large flocks can form). Their nest is merely a scrape in the ground where 3-4 eggs are laid between April-June as a single brood..
