Zino's petrel

Zino's petrel.
Zino's petrel (Pterodroma madeira) is a species of small seabird, endemic to Madeira. This gadfly petrel is grey above with a dark "W" across the wings. The wings are mainly blackish below, and the belly is white. It is very similar in appearance to Fea's petrel, both being formerly considered to be subspecies of the soft-plumaged petrel, but Zino's was raised to a species on criteria including morphology and mitochondrial DNA. Its breeding areas are a few ledges high in the mountains of Madeira, where it nests in burrows which are visited only at night. The single white egg is incubated by both adults, one sitting while the other feeds on fish and squid at sea. This species is subject to predation by introduced cats and rats, and in the past by humans. Predator control and the removal of grazing animals has enabled the population to recover although it remains listed as endangered on the IUCN Red List. There was a major setback in 2010 when fires killed three adults and 65 percent of the chicks.
