The spotted petrel ( Oceanites oceanicus ) is a very small species of the southern petrel family . It is one of the most common seabirds , with a population in the millions. The first description of the species was made in 1820 by Heinrich Kuhl under the name Procellaria oceanicus , mistakenly it was again described as a new species in 1824 by Charles Lucien Jules Laurent Bonaparte under the name Procellaria wilsonii . It is a very rare stray visitor in Europe, observed almost annually in the southwest and west of the coastal areas of Ireland and Great Britain since the 1970s.
description
When fully grown, the Buntfuß-Sturmschwalbe has a body length of 18 to 19 cm and a wingspan of 41 cm. The top is colored soot black. Above the rump is a clear patch of white feathers. The tail is black and cut straight.
Noticeable in flight are the feet, which are stretched out far over the tail. The webbed feet are yellow. The flight consists of short gliding phases and alternating loose wing beats. While foraging for food, the red-legged petrel hops and flutters along the water, paddling. It is believed that this behavior attracts prey .
distribution
Red-footed petrels breed on the Antarctic mainland, the Falkland Islands , Kerguelen , Heard and Bouvet in crevices or on moss pads. The diet consists mainly of krill , but also other crustaceans and squid. This species can live for around 10 years.
Way of life
In the Antarctic colonies, this species breeds in crevices in the rock or digs burrows in the soft earth. The clutch consists of a white-shelled egg with reddish-brown spots on the wider end. In the Falkland Islands, the breeding season lasts from December to April. From May onwards, there will be no more cortefoot petrels seen over the waters around the Falkland Islands. They then migrate to more northerly located oceans.
