So the end of the year 2015 is upon us. It was a great year for me in my quest to observe, hear and learn more about woodpeckers and the places where they live. I saw several species I had not encounted before, and got many photos and sound recordings, for example in the Philippines and Vietnam. Here is one of my favourites Luzon Flameback Chrysocolaptes haematribon, taken near Subic Bay, Philippines, in January. Many thanks to all of you who contributed images to this blog. And here is to 2016 and more even woodpeckers (Gerard Gorman).

Vietnam - Woodpeckers
I have just returned from Vietnam where, along with two friends, I explored three forested national parks: Cuc Phuong, Phong Nha-Ke Bang and Cat Tien. We observed a range of birds and other wildlife, including some rare primates, but our main objective was to find and study woodpeckers. There are 18 species of picid in Vietnam, and we observed 10 of them: White-browed Piculet Sasia ochracea, Grey-capped Woodpecker Dendrocopos canicapillus, White-bellied Woodpecker Dryocopus javensis, Lesser Yellownape Picus chlorolophus, Red-collared Woodpecker Picus rabieri, Laced Woodpecker Picus vittatus, Common Flameback Dinopium javanense, Pale-headed Woodpecker Gecinulus grantia, Bay Woodpecker Blythipicus pyrrhotis, Black-and-buff Woodpecker Meiglyptes jugularis. However, most of our time was concentrated on searching for and observing 2 species: the rare 'Near-Threatened' Red-headed, and the bamboo-dwelling Pale-headed. Both of these woodpeckers are rather shy, and often difficult to observe, the former inhabiting thick rainforest and the latter dense stands of mature bamboo, I was particularly pleased to obtain sound recordings of the call of Red-headed and drumming of Pale-headed.

Ivory-billed Woodpecker
This is as close as I have ever been to the Ivory-billed Woodpecker Campephilus principalis. Female (left) and male (right) specimens in the Vienna Museum of National History, Austria. The debate over whether this species still exists or not goes on, although it does not rage as much as it did in the years following reports of sightings in the USA in 2005 and 2005. The IUCN class this bird as Critically Endangered. It is, sadly, probably but not officially extinct.

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).

Name confusion - an example
Here is a pair of Eastern Grey Woodpeckers (Dendropicus spodocephalus) which I photographed at the SW edge of the Ngoronoro Crater, Northern Tanzania in February 2014. This taxon is also sometimes called Grey-headed Woodpecker, which can create confusion as that English name is also used for the Eurasian species Picus canus (this is also sometimes called Grey-faced Woodpecker). Further more, Dendropicus spodocephalus can also be found under a third name, Mountain Grey Woodpecker. In addition, Eastern Grey is sometimes placed in another genus, Mesopicos, rather than Dendropicus, and it is also sometimes treated as conspecific (lumped) with African Grey Woodpecker Dendropicus goertae or Mesopicos goertae if you prefer (which is also known as Grey Woodpecker). Confused yet ? Clearly, the current situation, where different taxonomic lists and field-guides use different English names (sometimes even scientific names) is far from ideal. Unfortunately, standardisation in the use of names for woodpeckers (and many other groups if birds) does not seem to be on the horizon.

Sexual Dimorphism in nestling woodpeckers
Most woodpecker species are sexually dimorphic, meaning simply that the sexes look different. This dimorphism varies: in some species it is obvious, in other more subtle (and in a few species it hardly exists). In some cases, plumage dimorphism becomes evident as soon as chicks begin to acquire feathers and young woodpeckers can be sexed visually before they leave their cavity. Here is an example, a female Williamson's Sapsucker (Sphyrapicus thyroideus) nestling, just before fledging (Oregon, USA, July 2014). Adults of this species are very different visually, in fact they are one of the most sexually dimorphic woodpeckers (so much so that they were once thought to be different species) and this is the case with nestlings, too.

Picid in Focus: Philippine Woodpecker
Philippine Woodpecker Dendrocopos maculatus. This is the race validirostris. Also commonly known as Philippine Pygmy Woodpecker and locally as just Pygmy Woodpecker. It is endemic to the Philippines, but is not found on all of the islands. Taken in La Mesa Park, Manila, January 2015 (Gerard Gorman).

Terrestrial Woodpeckers
There are several woodpecker species around the world that tend to forage on the ground and many others that, though essentially arboreal, will also occasionally drop to the ground to feed. Two species, however, are highly terrestrial, hardly ever using trees and seldom actually pecking wood! They are, the Andean Flicker Colaptes rupicola of the high Andes in South America & the Ground Woodpecker Geocolaptes olivaceus of Southern Africa. Here is a close-up of the former: a male of the puna race, in C Peru, November 2012 (Gerard Gorman).
