Soundscape Røst – The christmas sound-calender, # 3 & # 4

# 3 & # 4:

This recording, of one of my favourite seabirds the Fulmar,  is done on a fantastic, quiet late June evening out at sea. We have gone about 2o minutes past Skomvær lighthouse in the Røst archipelago and we are out in the boat fishing for dinner. As we (myself alongside biologist Tycho Anker-Nilssen and Magdalene Langset) came further and further out into the open sea, seing no land on neither side of the boat, only the slow continous waves, the Fulmars closed in and gathered around us. They where only accompanied by a few eager Kittiwakes. We turned off the boat motor and begun fishing, and they became more and more numerous. Finally we threw some saithe-gut out of the boat and I recorded just this moment using a Telinga Pro7 microphone.

About Fulmars from Wikipedia:

The Northern Fulmar, Fulmarus glacialis, Fulmar,[2] or Arctic Fulmar[4] is a highly abundant sea bird found primarily in subarctic regions of the north Atlantic and north Pacific oceans. Fulmars come in one of two color morphs: a light one which is almost entirely white, and a dark one which is uniformly grey. Though similar in appearance to gulls, fulmars are in fact members of the Procellariidae family, which include petrels and shearwaters. It and the Southern Fulmar (Fulmarus glacialodes) together comprise the only extant species in the genus Fulmarus.

The Northern Fulmar and its sister, the Southern Fulmar, are the extant members of the genus Fulmarus. The fulmars are in turn a member of the order Procellariiformes, and they all share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns; however, nostrils on albatrosses are on the sides of the bill, as opposed to the rest of the order, including fulmars, which have nostrils on top of the upper bill. The bills of Procellariiformes are also unique in that they are split into between 7 and 9 horny plates. One of these plates makes up the hooked portion of the upper bill, called the maxillary unguis. They produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is used against predators as well as an energy rich food source for chicks and for the adults during their long flights.[5] It will mat the plumage of avian predators, and can lead to their death.[6] Finally, they also have a salt gland that is situated above the nasal passage and helps desalinate their bodies, due to the high amount of ocean water that they imbibe. It excretes a high saline solution from their nose.[6]

The Northern Fulmar was first described as Fulmarus glacialis by Carl Linnaeus, in 1761, based on a specimen from within the Arctic Circle, on Spitsbergen.[4]
