Thursday 13th August comments: Fulmars are one of the longest lived seabirds in Britain, with an average lifespan of around 44 years. They are relative of the Albatross (a member of the tubenose family), fire oily vomit at predators, fly incredible distances and despite all this, are probably one of the most overlooked birds on the May. They are a very slow growing species and are one of the last seabirds to leave the island; with an average incubation of around 50 days and another 50 days of growing before the chick is ready to fledge.
They are the only species that have had a decline in their population this year, with a drop of 25 pairs, bringing the figure to a round total of 300 pairs breeding. However this is only a small fluctuation and can vary slightly year on year, with the highest recorded 382 (1997) to 198 (1990) and 218 (2013). The yearly average is around 300 pairs in recent years.
