Trocaz Pigeon Columba trocaz

Endemic to the island of Madeira, where it is largely restricted to native laurel and tree heath forests. Body is largely gray with a purple-pink breast, and a noticeable silvery patch with black streaks on the side of the neck. The iris is yellow with a red ring around the eyes. Compare with the only other pigeon on the island, the Rock Pigeon; note differences in structure, color, and habitat preference. Song is a series of very low, groaning coos.
