Known in the Falkland Islands as ‘firebirds’ for their habit of flying into flames, the Peruvian diving-petrel is easily attracted to light. Agile both in and out of the water, this species flies just above the water surface, travelling straight through waves with very fast wing beats. It is usually seen singly or in small groups when out at sea, and tends not to travel too far from the coast (3). On land however, the Peruvian diving-petrel nests in colonies, leaving them before sunrise to feed, and returning after dark (5). They feed opportunistically on small fish and crustaceans (2), diving to around 32 metres underwater, and up to an incredible 83 metres (6).
Breeding has been recorded in this species throughout the year, with least activity in November. It is thought to have two breeding periods each year, with some pairs breeding in both periods (2). A single egg is incubated for 9 – 10 weeks and the hatchling is fed by both parents until it fledges after 60 to 70 days (5).
