Climate change may well affect populations of seabirds in the northern Atlantic. The most important demographic may be an increase in the sea surface temperature, which may have benefits for some northerly Atlantic puffin colonies. [58] Breeding success depends on ample supplies of food at the time of maximum demand, as the chick grows.
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.
The male Atlantic puffin builds the nest and exhibits strong nest-site fidelity. Both sexes of the horned puffin help to construct their nest. Horned puffin burrows are usually about 1 meter (3.3 feet) deep, ending in a chamber, while the tunnel leading to a tufted puffin burrow may be up to 2.75 meters (9.0 feet) long.

Most species nest in crevices or burrows, and all but one species attend the breeding colonies nocturnally. Pairs form long-term, monogamous bonds and share incubation and chick-feeding duties. Like many species of seabirds, nesting is highly protracted, with incubation taking up to 50 days and fledging another 70 days after that.
