Woodpeckers of the World: Habitats: post burn forests

Habitats: post burn forests

Although forests that have burnt may seem disaster zones that are void of life, this is not the case. Bark- and wood-boring beetles thrive in the dead timber and subsequently attract woodpeckers. For example, this burn by Davis Lake in Oregon, USA, currently (July 2014) hosts Hairy and Lewis's Woodpeckers, Northern Flicker and Williamson's, Red-naped and Red-breasted Sapsuckers. The standing snags provide ideal nesting sites adjacent to the beetle food resources.

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.
