Birdfinding.info <\/em><\/strong>\u21d2<\/em><\/strong>\u00a0 For several decades, the Philippine-endemic Red-vented Cockatoo<\/strong> (known locally as the Katala<\/em><\/strong>) was severely persecuted for the illegal cagebird trade, and it is listed as critically endangered.\u00a0 Starting in 1998, an intensive conservation program launched by the Katala Foundation<\/strong><\/a> has produced localized increases, and a slow recovery seems to be underway.\u00a0 Its global stronghold is along the coasts of Palawan\u2014especially adjacent Rasa Island (open to visitors from July to December), which has become a source of immigrants to the main island around Narra.\u00a0 A flock inhabits the Iwahig Penal Colony property near Puerto Princesa, and can sometimes be seen visting parks and gardens of the city.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Occurs in humid lowland forests, including second growth and degraded woodlands, mainly in coastal areas with mangroves and nearshore islets where it can roost and nest in seclusion.\u00a0 Often feeds in corn and rice fields, a habit that has contributed to its persecution.<\/p>

In 2016, the global population was estimated at 650-1,120 birds, with the majority (580-850) on Palawan and adjacent islets: mainly Rasa, Pandanan, and Dumaran.\u00a0 The next-largest remnant population was an estimated 50-150 on the Sulu Islands: mainly Tawitawi.<\/p>

Much smaller groups (each about twenty or fewer) have persisted, at least into the 2010s, on Polillo, Bohol, and northern Samar.\u00a0 In the southeast, Siargao (northeast of Mindanao) has been selected as a reintroduction site.<\/p>

The Rasa Island population numbered 23 individuals in 1998, but conservation measures enabled it to recover to 200 by 2008, 300 by 2015, and approximately 400 in 2019.\u00a0 In 2011 alone, the island produced at least 75 juveniles.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The Pandanan Island population was approximately 40 in 2008, but protection against capture of chicks from the nests had enabled it to rebound to approximately 300 by 2018.\u00a0 The conservation project has been expanded to adjacent Bugsuk Island.<\/p>

Formerly inhabited the entire Philippine archipelago north to the Manila area.\u00a0 Populations were generally intact until at least 1950.\u00a0 Trapping escalated substantially in the 1970s, but it remained fairly common across much of its range into the early 1980s.\u00a0 By the late 1980s, however, it had become rare and localized.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
