Status and Conservation
Barau's Petrel is considered to be an endangered species. It has a highly restricted breeding range and has suffered hunting pressure in the past. While the shooting of the species has now been stopped, and the population seems to have recovered, it is currently threatened by introduced species and light pollution. Young birds, particularly fledglings, are disorientated by artificial lights such as streetlights or the floodlights of sporting venues, which they mistake for bioluminescent squid, and lead them to fail reach the sea. It is estimated that as much as 40% of each breeding season's fledglings get confused in this fashion. Conservation organisations work with local people to catch disorientated chicks and release them back at sea, a program that is thought to rescue most of the lost chicks. Measures are also underway to reduce light pollution by shielding light sources so that they don't attract young birds, a method that has been used to help Newell's Shearwaters in Hawaii.

Famous quotes containing the words status and/or conservation:
“[In early adolescence] she becomes acutely aware of herself as a being perceived by others, judged by others, though she herself is the harshest judge, quick to list her physical flaws, quick to undervalue and under-rate herself not only in terms of physical appearance but across a wide range of talents, capacities and even social status, whereas boys of the same age will cite their abilities, their talents and their social status pretty accurately.”
—Terri Apter (20th century)
“The putting into force of laws which shall secure the conservation of our resources, as far as they may be within the jurisdiction of the Federal Government, including the more important work of saving and restoring our forests and the great improvement of waterways, are all proper government functions which must involve large expenditure if properly performed.”
—William Howard Taft (1857–1930)
