They also educate about the dangers that the birds are facing and research ways to implement protection for them in the future. Considering their populations numbers are high, their declining population is thought to be due to the mortality rate of eggs and young. 246:, with most records at sea being to the west of the breeding islands, and along the subtropical convergence. Adults are about 43 cm long, powerful, large, stocky, dark in color with white belly. Their head can appear to be grey in worn plumage. Brown undercoating of wings and tail. These petrels can live on average of 15 years of age. 258:. It is restricted to just two breeding islands and has declined historically due to exploitation for food. According to some studies, there are roughly 1.1 million mating pairs, but only about 25% of eggs survived. This is making their large population numbers decrease rapidly. 357:, minimizing the risk of introducing other invasive species, and finding methods better to understand the Atlantic petrel's habits. Demographic mapping is being used to better understand the island and its animal population trends. 309:, which prey on recently-hatched chicks. Mouse predation is particularly prevalent on Gough Island, whose mice have rapidly evolved to be about twice the size of their mainland counterparts through a phenomenon commonly known as 316:
Given their small breeding range, severe hurricanes also pose an intermittent threat to breeding populations. Increasingly severe storms also threaten the availability and predictability of food sources such as squid.
