Woodpeckers as indicators of natural forest ecosystems

WeißrückenspechtCentral Europe is an old cultural landscape in which practically no area has been able to preserve its natural state. The far-reaching anthropogenic changes also affect the remaining type of forest strongly, that it is not known exactly what they look like under natural conditions. Largely unchanged forests can only be found on small remaining areas in some higher mountains and in the far east of Central Europe. Naturally, around 95% of Germany’s area would be covered with forest. The European beech or Common Beech (Fagus sylvatica) would probably occupy around 70% of the country’s area as the predominant tree species in western Germany. Due to their specific diet and the associated high degree of specialization, woodpeckers are particularly suitable as indicators for near-natural forest ecosystems. From this, the anthropogenic changes in the forests can be derived. The wealth of woodpecker species in Europe reflects quite well the strength of human influence on the originally forested landscapes. In almost all European countries, the clade of woodpeckers would probably be represented with 7 to 8 species if there would be still larger natural forest areas. The sensitivity of the woodpecker to habitat changes and thus its suitability as an ecological indicator increases with the degree of specialization and ranges from the “habitat generalist” Great Spotted Woodpecker (Dendrocopos major) to the highly endangered White-backed Woodpecker (Dendrocopos leucotos) and Three-toed Woodpecker (Picoides tridactylus).

Several studies, among others in the Bialowieza forest show that the White-backed Woodpecker is the most sensitive species of woodpeckers. It can only find optimal conditions in strictly Continue reading Woodpeckers as indicators of natural forest ecosystems

Hazel Grouse: the results

Haselhuhn, MännchenIn total we visited 5 different locations where the local guides had encountered several individuals of the Hasezl Grouse the last weeks or even years. The last encounter sometimes was only 3 days before. 4 of the locations were locations like a lek – where you could hear the mating song and the mating Continue reading Hazel Grouse: the results

Hazel Grouse: the hide

Tarnzelt in HaselhuhnhabitatAdditionally finding Hazel Grouse means knowing the behavior of the Hazel Grouse. E.g. the Hazel Grouse is – although a shy bird – quite responsive or even aggressive during the mating season which has a first peak in September and then again in March/ April. In this time you can hear the mating call or mating song of the male. Best is the time in the early morning, but actually they are calling/ singing the whole day – in the right mood in the right environment.

The search for direct and indirect references to the Hazel grouse is difficult due to its hidden and secret life.

The classic approach: visual observations. Many people Continue reading Hazel Grouse: the hide

Hazel Grouse: the habitat

HaselhuhnhabitatFinding Hazel Grouse is equivalent of knowing the habits of the Hazel Grouse which means also knowing and recognizing the habitat of the Hazel Grouse. The search for the right habitat is not eased by the fact, that the Hazel Grouse has at least 3 different habitat requirements during the year in the different seasons. In general the Grouse prefers the following habitat structures. Young forest stages with pioneer forest character. A high percentage of soft wood species like Continue reading Hazel Grouse: the habitat

Finding Hazel Grouse in the Carpathians

HaselhuhnHazel Grouses (Bonasa bonasia) are certainly one of the most thought-after bird species for naturalist and bird photographers in western Palearctic. This is in parts due to the fact, that this bird is one of the few autochthon representatives of the Phasianidae family in Middle Europe. And: actually it is a very beautiful bird. Unfortunately – or maybe fortunately for the keen photographer – it is a difficult bird to observe or even photograph. In so far, not too many images are available, especially photos of the Continue reading Finding Hazel Grouse in the Carpathians
