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.
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 ...
The Atlantic puffin (Fratercula arctica), also known as the common puffin, is a species of seabird in the auk family.It is the only puffin native to the Atlantic Ocean; two related species, the tufted puffin and the horned puffin being found in the northeastern Pacific.
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.
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 ...
Unusual nest sites include hay bales, a stump 0.6 m (2 ft) above the water, and floating logs or vegetation. There is a record of a common tern taking over a spotted sandpiper nest and laying its eggs with those of the wader . [ 60 ]
The Manx shearwater (Puffinus puffinus) is a medium-sized shearwater in the seabird family Procellariidae.The scientific name of this species records a name shift: Manx shearwaters were called Manks puffins in the 17th century.
Many types of seabirds are vulnerable to injury and death as a result of being attracted to artificial lights at night. This is a particular threat for petrels and shearwaters. [ 27 ] Burrow-nesting seabirds like the Westland petrel returning to their burrows at night, or leaving them before dawn, can become disoriented by artificial lights and ...
