Literature: Smithsonian Field Guide
The Smithsonian Field Guide to the Birds of North America by Ted Floyd (Harper Collins, 2008) has a superb cover photo of a Red-headed Woodpecker Melanerpes erythrocephalus. A total of 22 picid species (woodpeckers, sapsuckers and flickers) are covered in the book with fine photographs and range maps.

Photos Needed !
I posted a while ago a request for photos for my forthcoming book on world woodpeckers (see info in the left-hand column here). One change is that sample photos can now be sent directly to me in small jpgs. In particular, woodpecker species from Africa and South & Central America are needed. Both sexes, distinct races, juveniles, interesting poses, behaviour shots, all are needed. Thanks. Gerard Gorman.

Woodpecker Flight
The line 'typical woodpecker flight' is often used in the literature. It is used to describe a bounding, undulating flight style. However, many woodpeckers do not fly in this way. The larger species in particular do not bound but rather move in a fairly straight, steady line, flapping in a manner not unlike that of a crow. Black Woodpecker in flight taken by Colin Brown, Hungary, August 2012.

Literature: Downy Woodpecker - Wild Bird Guides
This excellent monograph on Picoides pubescens by Gary Ritchison includes some great photos of North America's smallest woodpecker species. The book is fact-filled, with just about all the natural history of the species covered, but it is not overly scientific and so is a book for all fans of woodpeckers. Published by Stackpole Books, USA, in 1999.

Picid in Focus: Black-cheeked Woodpecker
Black-cheeked Woodpecker Melanerpes pucherani is a typical, gregariousl, noisy member of the genus. It is monotypic and occurs from southern Mexico through Central America to Colombia and Ecuador. It often visits feeders. Photo of this female (males have all-red crown) taken In Costa Rica by Gerard Gorman.

Picid in Focus: Tullberg's Woodpecker
Female Tullberg's Woodpecker Campethera tullbergi. This canopy forager is often inconspicuous as it works snags and probes in moss,
lichen and leaf-clusters for prey. Three races: nominate tullbergi in south-east Nigeria, western Cameroon and Bioko Island in Gulf of Guinea, taeniolaema
(as here) from eastern
DR Congo to Rwanda, south-western Uganda, Burundi, western Tanzania and western Kenya, and hausburgi in the Kenyan
highlands east of Rift Valley, eastern Uganda and northernmost Tanzania. Photo by Gerard Gorman, Uganda, February 2012.

Primary and Secondary Cavity Use
Woodpeckers are almost unique in that they are primary cavity users. That is, they create their own holes for use as nesting and roosting sites. But not all woodpeckers do this, some are secondary cavity users. The two species in the genus Jynx, the wrynecks, do not excavate holes. For example, the Eurasian Wryneck Jynx torquilla in this photo used the old nesting cavity of a Middle Spotted Woodpecker Dendrocopos medius in which to breed. The Middle Spotted had created and bred in the cavity the previous year. Some species also re-use their holes and those made by others. Photo: Bukk Hills, Hungary, June 2012, Gerard Gorman.

Picid in Focus: Acorn Woodpecker
Acorn Woodpecker Melanerpes formicivorus is a stunningly plumaged woodpecker. It occurs from the western USA to Colombia. Some populations are migratory. Often found in oak and pine-oak woods. Known for its habit of storing acorns in larders, each acorn in one specially made hole. Photo taken In Costa Rica, Gerard Gorman:

Habitats: Dying Spruce Forest
This photo shows a dying mixed spruce-beech-fir forest. After a fire or an avalanche (as in this case), most beech trees fall and the damaged, broken standing spruces become infested with bark-beetles, especially Ips species. Such forests are major feeding habitat for woodpeckers, especially Eurasian Three-toed Woodpeckers which subsequently invade and breed in high densities. Photo taken in the Austrian Alps, April 2012, Gerard Gorman.

Genus: Dendropicos
This genus is currently composed of 15 (taxonomy in dispute) small to medium sized, typically green and grey coloured species. All are found in woodlands and forests in Africa. Sexual dimorphism is shown in males having red or yellow on the crown, which females lack. This male Grey Woodpecker Dendropicos goertae was photographed in Uganda in March 2012, Gerard Gorman.

The full title of this book by Stan Tekiela is Remarkable Woodpeckers: Incredible Images and Characteristics. The book does indeed contain some stunning photographs of 22 picid species from Canada and the USA, mostly by Stan Tekiela himself. Though the photography dominates, there are also many short paragraphs on various aspects of woodpecker natural history. Published by Adventure Publications Inc. Cambridge, MN, USA.

Picid in Focus: Green-barred Woodpecker
Green-barred Woodpecker Colaptes melanochloros occurs in South America, south of the equator, in parts of Brazil, Paraguay, Uruguay, Bolivia and Argentina.

Literature: The Red-cockaded Woodpecker
This full title of this important book by Richard N. Conner, D. Craig Rudolph and Jeffrey R. Walters is The Red-cockaded Woodpecker: Surviving in a Fire-maintained Ecosystem. The authors document the story of this endangered picid, covering just about every angle there is in great detail, from history, evolution, behaviour, ecology, forestry, conservation and the associated politics. All in all, essential reading. Published by University of Texas Press, Austin, USA, in 2001.

Literature: Woodpeckers of Eastern North America
This book by the late Lawrence Kilham was first published in 1983 by the Nuttall Ornithological Club, then later re-issued by Dover Publications, New York, in 1992. It is out-of-print but still fairly easy to find. It is a great book by a great observer of woodpeckers. It mainly covers Downy, Hairy, Black-backed, Pileated, Red-headed and Red-bellied Woodpeckers, Yellow-bellied Sapsucker and Northern Flicker, and to a lesser extent Crimson-crested and Pale-billed Woodpeckers. It is fact-filled, the facts mostly established by the author himself over years of devoted observation and study of both wild and captive picids.
