times of the white-bellied storm petrel, but extrapolations from cogeners postulate a generation time of 15.2 years (assuming “an average age at first breeding of 4.7 years, an annual survival of adults of 87.8% and a maximum longevity of 30.4 years ”). Food and feeding Small crustaceans, small squid and sea skaters have been identified as dietary components. Feeding occurs by skimming across the water and dipping to catch their submarine mark near the surface. Young are fed by both parents with crustaceans and squid. Population The quality of data on which population estimates are based is recognised to be poor and unreliable. In 2004 Brookes estimated the global population of Fregetta grallaria to be some 300,000, a population thought to be likely in decline as a result of predatory invasive species. The global population of Fregetta grallari grallaria is estimated at 2,500 pairs. An estimated 1,000 breeding pairs of Fregetta grallari grallaria (Tasman Sea) nest in the Lord Howe Island group but are now extinct on the main island. Tasman Sea which may be a subspecies, F. g. grallaria. Populations of Fregetta grallaria grallaria and Fregetta grallaria titan in the eastern Pacific have been described as “meagre”. The white-bellied storm petrel is considered to be rare in New Zealand with an estimated 700 nesters. Conservation status Significant deficiencies in the data sources that inform these decisions are well-recognised. The IUCN Red List evaluates Fregetta grallaria as being of least concern based on range size, population trend, and population size criteria. In New Zealand, its conservation status is nationally endangered (2013). In Australia, the commonwealth status listing of F. grallaria is vulnerable. Nationally in Australia, the Environmental Protection and Biodiversity Conservation Act statutory listing status is vulnerable and requires a recovery plan (2009). Its nonstatutory listing under the NGO Action Plan for Australian Birds 2010 is vulnerable. In New South Wales, Australia, at the state level, F. grallaria is listed as vulnerable under the Threatened Species Conservation Act 1995. F. g. gallaria (Tasman Sea) is “considered to be vulnerable at the global level”. The Australian breeding population is listed as vulnerable (“small populations at five locations with plausible future threat”) and the population visiting Australian territory as near threatened (“seven locations with plausible future threat”) under the Action Plan for Australian Birds 2010. All existing breeding populations are now important to long-term survival. The natural history of the seabird (longevity,
