Seabird mortality caused by long-line fisheries can be greatly reduced by techniques such as setting long-line bait at night, dying the bait blue, setting the bait underwater, increasing the amount of weight on lines and by using bird scarers, [104] and their deployment is increasingly required by many national fishing fleets.
Fowlsheugh Nature Reserve, Aberdeenshire, Scotland. Fowlsheugh is a coastal nature reserve in Kincardineshire, northeast Scotland, known for its 70-metre-high (230 ft) cliff formations and habitat supporting prolific seabird nesting colonies.
They nest in burrows and often give eerie contact calls on their night-time visits. They lay a single white egg. They lay a single white egg. The chicks of some species, notably short-tailed and sooty shearwaters, are subject to harvesting from their nest burrows for food, a practice known as muttonbirding , in Australia and New Zealand.

The short-tailed shearwater or slender-billed shearwater (Ardenna tenuirostris; formerly Puffinus tenuirostris), also called yolla or moonbird, and commonly known as the muttonbird in Australia, is the most abundant seabird species in Australian waters, and is one of the few ...
The Swiss naturalist Conrad Gessner gave the northern gannet the name Anser bassanus or scoticus in the 16th century, and noted that the Scots called it a solendguse. [4] The former name was also used by the English naturalist Francis Willughby in the 17th century; the species was known to him from a colony in the Firth of Forth and from a stray bird that was found near Coleshill, Warwickshire.
The colony is at its most active in the evening, with birds standing outside their burrows, resting on the turf, or strolling around. Then, the slopes empty for the night as the birds fly out to sea to roost, often choosing to do so at fishing grounds ready for early-morning provisioning. [16]: 44–65

The majority of procellariiforms nest once a year and do so seasonally. [69] Some tropical shearwaters, like the Christmas shearwater, are able to nest on cycles slightly shorter than a year, and the large great albatrosses (genus Diomedea) nest in alternate years (if successful). Most temperate and polar species nest over the spring-summer ...
