Holes (for nesting and/or roosting) made by Andean Flicker (Colaptes rupicola) in the mud brick wall of a house. In village in the Andes, Peru. October 2016. This highly terrestrial woodpecker rarely pecks in wood!
This recently published book contains 8 papers by different authors on a range of subjects including woodpecker systematics, morphology, cognition, ecology, breeding biology and population densities. It is edited by Hans Winkler and published by the Biologiezentrum des Oberosterreichischen Landesmuseum in Linz, Austria. I am honoured to have a paper of my own included: Foraging signs and cavities of some European woodpeckers (Picidae): Identifying the clues that lead to establishing the presence of species.

Adult male West Indian Woodpecker Melanerpes superciliaris. Males have an all red crown, whereas females are red only on the nape. This is the nominate race superciliaris which has much black around the eyes. Photo by Gerard Gorman, Cuba, March 2016.
This is a female (note the white throat) Yellow-bellied Sapsucker (Sphyrapicus varius). Note the sap wells on the coco-palm tree. This species does not breed in Cuba, but winters in good numbers. The hole is probably not hers. Photo: Gerard Gorman, March, 2016, in Cuba.
Check out the wonderful work of Finnish cartoonist Seppo Leinonen. His cartoons highlight, with humour, some of the key issues facing forests (and other habitats). He is also big fan of woodpeckers! http://www.seppo.net/e/
