Imperial Woodpecker on Film

An article in the The Auk (128 (4): 671-677, 2011) entiltled FILM DOCUMENTATION OF THE PROBABLY EXTINCT IMPERIAL WOODPECKER (CAMPEPHILUS IMPERIALIS) is essential reading for all picid enthusiasts. The Imperial Woodpecker of Mexico was the largest woodpecker in the world until it became extinct (probably) in the late 20th century. This paper describes a recently discovered 16-mm colour film of the species taken in 1956 by the late William L. Rhein.

Woodpeckers as keystone species


Animals that play important roles in the lives of others in an ecological community are known as keystone species. Many woodpeckers are keystones, as some birds, mammals and invertebrates benefit from the cavities that they create. Indeed, some species can be highly dependent upon woodpeckers for nesting or denning sites. Birds and mammals that do not excavate holes themselves, but use those made by others for nesting or roosting, are called secondary cavity-usersIn some cases the local populations of secondary-cavity using birds can even be determined by the availability of woodpecker holes. Birds that use woodpecker cavities include titmice, flycatchers, hirundines, ducks, kestrels, owls, doves, parrots, trogons and even large species of toucans and hornbills.

Picid in Focus: Knysna Woodpecker

Knysna Woodpecker Campethera notata is endemic to South Africa. The sexes differ slightly with males (as in this photo) having an all-red-crown and nape and a red malar stripe, whilst female has red only on the hind-crown and an indistinct black malar. It is classed as 'near threatened' due to having a restricted range. The species is found in coastal, lowland, evergreen woodlands, scrub, bush and thickets, especially with euphorbia and milkwood, mainly along the Eastern Cape but also northwards into southern KwaZulu-Natal.

Habitats: Bamboo - Bambuseae

There are around 1450 species of bamboo (an evergreen member of the grass family) around the world. Many occur in tropical regions, mainly in SE Asia but also the Americas and Africa, and some in temperate regions. As a habitat for picids, bamboo may not immediately spring to mind, however many piculets and some true woodpeckers forage and nest in bamboo. Others, such as the appropriately named Bamboo Woodpecker Gecinulus viridis of south-east Asia, specialise in this habitat. For many species bamboo is also a favoured substrate upon which to drum as it resonates very well, especially when mature or dead. Photo taken in northern Malaysia, Gerard Gorman.

Status: Great Slaty Woodpecker - Vulnerable

This magnificent species Mulleripicus pulverulentus is the biggest picid in the Old World. It occurs in south-east Asia from the Himalayas to Indonesia. It is a social, gregarious woodpecker which forages in extended family parties of from 2 to 12 individuals, some of which also have roles as helpers at the nest. It's conservation status was changed from Least Concern to Vulnerable in 2010 after it became clear that a drastic decline in numbers had occurred in recent decades. This was mainly due to the loss of primary forests in some parts of its range and it is not inconceivable that this decline has been even more severe than estimated. Thanks to Martjan Lammertink for this fine photo: for more see PicidPics.

Conservation: Helmeted Woodpecker Dryocopus galeatus

FUNDING NEEDED ! Although rare and declining, the Helmeted Woodpecker can still be saved if the old forests that it prefers are conserved and if forest conditions for it are improved in logged forests. To find out the ecological needs of the Helmeted Woodpecker and to implement habitat restoration for it and associated old-forest species, a five year conservation project is now being launched by Martjan Lammertink. It is a joint project by the Cornell Lab of Ornithology, the National Research Council of Argentina (CONICET), and the ParanĂ¡ Pine Project, a local NGO in Misiones province, Argentina. The project needs funds to cover radio tracking equipment and field expenses and to pay field assistants and Argentinean students. Fundraising from foundations for a little known Neotropical woodpecker is hard, and Martjan would very much appreciate donations from readers of this blog for the project. This photo of a female was taken in the Cruce Caballero Provincial Park, Misiones, Argentina by Martjan Lammertink: see PicidPicsFor more information, or to donate, please contact Martjan at: jml243@cornell.edu

Status: Helmeted Woodpecker - Vulnerable

This species (on average the smallest of the Dryocopus) is one of the rarest woodpeckers in the Neotropics. It occurs only in South America's Atlantic Forest, one of the world’s most endangered wooded ecosystems, and has seriously declined in number due to loss of habitat. Today probably less than 12% of the Atlantic Forest region remains. The global population estimate is 2500-9900 and it is regarded as Vulnerable. This recent article is essential reading: Lammertink, M., A. Bodrati & R. E. Santos (2011): Helmeted Woodpecker Dryocopus galeatus: a little-known Atlantic forest endemic.

Literature: The Travails of Two Woodpeckers: Ivory-bills & Imperials

This book examines the history of the declines of two of the world's largest woodpeckers: Campephilus imperialis and C. principalis. The causes of decline and the question of whether these birds are extinct or not is discussed in detail. The authors (Noel F. R. Snyder, David E. Brown and Kevin B. Clark) take the view that these species are sadly extinct. Published in 2009 by the University of New Mexico Press, USA.

Habitats: Taiga Forest

The Taiga is a belt of forest that runs across the boreal (sub-Arctic) latitudes of the northern Hemisphere. Coniferous trees dominate in the Taiga with various spruce, larch, fir and pine typical. Deciduous trees, which are more common in the primary and secondary succession stages of growth, are alder, aspen and birch. In Eurasia typical woodpeckers of this habitat include Eurasian Three-toed Woodpecker. In North America Black-backed and American Three-toed Woodpeckers are typical. 

Tuesday, 1 March 2011

Genus: Campethera

This genus is composed of 12 species, all found in sub-Saharan Africa. All are greenish on the upperparts. Though not truly terrestrial the Campethera readily forage on the ground for termites and the like and their bodily structure and bill reflects this. This female Bennett's Woodpecker C.bennettii was photographed in the Kruger NP, South Africa, by Gill Marven.

Nomenclature: the problem of vernacular names

A universal agreement amongst ornithologists on which taxonomy to use in the classification of birds still eludes us. Furthermore, there is still disagreement on which English vernacular names to use and this is valid for the woodpeckers, too. This problem is partly due to the global diversity of the English language and a standardization of names does not seem to be on the horizon. Indeed, total conformity in English nomenclature is probably unrealistic. The solution for most when discussing the picids (to establish exactly which species is being discussed) is to refer to the scientific name of the species (often called the Latin name, though strictly speaking that is incorrect) as there is more (but not total) conformity in the use of scientific names. There are may examples of woodpeckers having more than one English name as even a brief perusal of the literature will reveal. For example, in India the Flamebacks are also often called "Goldenbacks". A particularly confusing example is "Grey-headed" versus "Grey-faced" Woodpecker. Most European literature, and the vast majority of ornithologists and birders, refer to the Eurasian Picus canus as Grey-headed Woodpecker, however the African species Dendropicos spodocephalus is also widely called Grey-headed Woodpecker (the IOC have named it Eastern Grey Woodpecker).
