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.
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.
Adult near Burrow on Bruny Island. The photograph was taken at night. Fledgling, Austins Ferry, Tasmania, Australia. 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 ...
A few species nest in small or dispersed groups, but most breed in colonies of up to a few hundred pairs, often alongside other seabirds such as gulls or skimmers. [5] Large tern species tend to form larger colonies, [ 18 ] which in the case of the sooty tern can contain up to two million pairs.

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 ...

Both parents take turns incubating the egg over about 41 days, and spend another forty days raising the chick. The fledgling leaves the nest alone and at night, making its way towards open water, then quickly dives and swims away to begin independent life. [18] [19] Rises in ocean temperature have increased the reproductive rate of the horned ...
