MINDANAO BROADBILL Eurylaimus steerii Critical — Endangered — Vulnerable A1c; A2c; C1; C2a This species qualifies as Vulnerable because it has a small, seriously fragmented population and is declining rapidly as a result of lowland deforestation. DISTRIBUTION The Mindanao (Wattled) Broadbill or Steere’s Broadbill (see Remarks 1) is endemic to the Philippines, where it occurs in two races on four main islands: mayri on Dinagat (plus the tiny island of Poneas midway to Siargao), Siargao and Mindanao (excluding the Zamboanga Peninsula), and nominate steerii on Basilan plus the small offshore island of Malamaui, and the Zamboanga Peninsula on Mindanao. Lambert (1996) pointed out the apparent absence of records from the western part of southern Mindanao. On the other hand, the species seems very likely to occur on Bucas Grande island between Siargao and Mindanao.
