Sunda Woodpecker and the Wallace's Line

Sunda Woodpecker Dendrocopos moluccensis is found in SE Asia in Malaysia (mainland and islands) and Indonesia (Great and Lesser Sundas). Interestingly the grandis race of this species is the only woodpecker that occurs south of the Wallace's Line, in the Lesser Sunda Islands. This photo of a nominate race female was taken in Sabah, Borneo by Neil Bowman in 2010.

Picid in Focus: Philippine Woodpecker

Philippine Woodpecker Dendrocopos maculatus. Endemic to the Philippines - this great photo of an adult female was taken by Alain Pascua in October 2011, in Marikina City. See more of Alain's wonderful bird images at: http://www.alainpascua.com

Background

Woodpeckers, the Picidae, are Piciformes, an order that includes some of the oldest avian lineages. The Piciformes probably originated about 60 million years ago in the Tertiary period and became distinct from their closest relatives some 50 million years ago. Depending upon which taxonomy is followed, and the fact that the status of some species is unclear, around 240-260 woodpecker species probably exist globally. The Picidae includes three subfamilies: Jynginae (wrynecks), Picumninae (piculets) and the Picinae, the “true woodpeckers”. In terms of size, behaviour, distribution and the habitats they use, the Picinae are a fairly diverse group of birds with six distinct tribes. They are widespread and found from sea-level to high-altitudes but absent from the Arctic, Antarctica, Australia, New Zealand, Papua New Guinea, Madagascar and some other islands. Worldwide woodpeckers are usually, but not exclusively, associated with trees.
