2021Madeira - Europa - Endangered National Wildlife - First Day Cover

Zino’s petrel or freira (Pterodroma madeira) feeds over a wide area in the central and eastern Atlantic Ocean, since it winters in the open sea. However, it only nests in the eastern part of Madeira Island, in burrows dug into the soil of mountainous areas above 1600 m in altitude; for this reason, it is considered endemic to this archipelago. During the breeding season these birds congregate in the ocean waters of Madeira and the Azores.
