“Yaffle” was one of the English folk names given to the European green woodpecker (German Grünspecht; Latin Picus viridis) due to its distinctive, laughing call.
The European green woodpecker spends most of its time foraging on the ground instead of pecking holes in trees as most other woodpecker species do. The bird primarily eats ants because its tongue is well adapted for this, being 10cm long and sticky (see this short video for a view of the bird’s impressive tongue). This woodpecker’s tongue is so long, in fact, that it wraps around the bird’s brain when retracted. The European green woodpecker will eat other insects, especially flies, mosquitoes and spiders, and will also occasionally eat rowan berries, cherries, apples, or grapes.
The European green woodpecker prefers semi-open landscapes, especially the edges of woodlands, hedges, orchards, parks, and large gardens with mature trees. It shows a strong preference for areas with a majority of deciduous trees and, therefore, in primarily coniferous areas it is rare to encounter one. Having a wide distribution in Europe, the European green woodpecker has an estimated population of 860,000 breeding pairs, which are territorial and rarely move more than 500m between breeding seasons.
Grünspecht is German for European Green Woodpecker
One of the reasons that the Grünspecht was chosen as Germany’s “Bird of the Year” in 2014 is that it has a strong affinity for the habitat of mixed orchards (Streuobstwiesen). While the commercial production of fruit is easier on a plantation, biodiversity is lower than in mixed orchards. The grass in these mixed orchards is mowed usually only twice a year, which contributes to them having a high density of ants and, in turn, makes the mixed orchards very attractive to the European green woodpeckers. Additionally, the trees found in mixed orchards are typically much taller and older than those on fruit plantations, and they often have hollows that provide perfect nesting locations. An informative German-language video can be viewed here.
My photos show a pair of European green woodpeckers, which I found in an orchard near Herrenberg, Germany. As you can see, the male and female are quite similar. The male has a red stripe near the beak whereas the female has all black coloration.
Fortunately for me, my area of Germany still has a good number of mixed orchards instead of the more monocultured fruit plantations found in other regions. Of the approximately 3,000 different types of apples grown in central Europe, only 60 varieties are commonly sold in German shops. Mixed orchards preserve many of these other varieties and are an important genetic reservoir. Consumers in Germany can support the mixed orchards, and thus the European green woodpecker, by purchasing juices made from these fruits, something that is offered quite frequently in my area (Baden-Württemberg).
