Great Spotted Woodpecker (Dendrocopos major) Science Article 1 abstract Forest fragmentation leads to a decrease in total forest area and patch size, which enhances predation pressure on birds’ breeding success. Existing data suggest that because hole nesters occupy relatively safe nest sites, their breeding success is not negatively affected by this process. However, fragmentation effects […]

Reproductive decisions of boreal three-toed woodpeckers (Picoides tridactylus) in a warming world: from local responses to global population dynamics
Eurasian Three-toed Woodpecker (Picoides tridactylus) Science Article 1 abstract Here, I examine whether both nestling prey abundance and profitability affect the timing of reproduction and hence the number of fledglings of three-toed woodpeckers, Picoides tridactylus. Individuals living in eastern Finland reproduced earlier and reared larger broods in habitat patches where the bark-beetle community developed earlier […]
Breeding performance, natal dispersal, and nest site fidelity of the three-toed woodpecker in the German Alps
Eurasian Three-toed Woodpecker (Picoides tridactylus) Science Article 2 abstract I studied the breeding biology of the three-toed woodpecker Picoides tridactylus in order to determine factors that influence annual and seasonal variations. Data from 37 pairs showed that 79% of nests produced at least one fledgling. The median laying date was not affected by elevation, and […]
Habitat use, home ranges and census techniques in the Black Woodpecker Dryocopus martius in the Alps.
Black Woodpecker (Dryocopus martius) Science Article 1 abstract We focused upon habitat use and home range size variation in an alpine population of the Black Woodpecker Dryocopus martius. Habitat selection analyses showed that the dominant local forest type, i.e. Mountain Pine Pinus mugo uncinata, was significantly avoided. Scots Pine Pinus sylvestris stands were positively selected, […]
