    RUFOUS-HEADED HORNBILL

    Population: 1,000–2,499 adult birds

    Habitat: Rainforests in the Western Visayas region of the Philippines

    Why They Are Endangered: A combination of deforestation and hunting for food and pet trade has affected the hornbill's population decline. In addition, Rufous-headed hornbills reproduce rather slowly. As a result, this bird is extinct on one of the three islands it is known to live on in the Philippines. Little else is known, due to lack of sightings and research. (Bird Life)
