Social Woodpeckers: Magellanic Woodpecker

Some woodpeckers are, to varying degrees, social in nature. One such species is the Magellanic Woodpecker Campephilus magellanicus of South America which is often seen in foraging family clans of 3-5 individuals. Young Magellanics may remain in contact with their parents for 3-4 years after fledging. These three, one male above and one below a female, were photographed in Argentina in December 2010 (Gerard Gorman).

Picid in Focus: Yucatan Woodpecker

Yucatan Woodpecker Melanerpes pygmaeus. This is a male, females have less yellow in the face and red only only on the nape. Photographed in Belize by Vaughan Ashby during a Birdfinders tour in March 2015.

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.
