Only a stump of the once proud birch has remained since the last storm. Even before that, drought had caused the birches in the area to die off. Now there are many birch stumps next to one that has already peeled off the bark. It’s hard to believe that an this stump can still be home for animals. One quickly associates woodpeckers with cave building,. This is what makes woodpeckers so special in forests. They belong to one of the very few groups of birds that can do this. And for this they have special adaptations in their skulls too. Smaller woodpeckers often use dead trees that are already quite rotten to build their caves. The Lesser Spotted Woodpecker (Dendrocopos minor), for example, needs soft, easy-to-work wood for its breeding cave. These lightweight caves are not permanent and are usually only suitable for one breeding season. But there are also two small tit species in our forests that create tree hollows: the Willow Tit (Poecile montanus) and the Crested Tit (Lophophanes cristatus). Because of their small body size and their dainty bills, they can only work on soft, heavily dried wood from willow, poplar or birch. In this respect, the demands of the Willow Tit and the Crested Tit do not differ significantly from those of the Lesser Spotted Woodpecker, which is also only sparrow-sized. Birch stumps are right at the top of the popularity list of tits, because the elastic and fairly weather-resistant bark of the birch gives even heavily rotten trunks considerable stability.
