Characteristics of trees preferred by foraging Middle Spotted Woodpecker Dendrocopos medius in northern Switzerland

Middle Spotted Woodpecker (Dendrocopos medius) Science Article 4 abstract The endangered Middle Spotted Woodpecker Dendrocopos medius is restricted to oak forests. We analysed this woodpecker’s foraging trees and behaviour in a coppice-with-standards wood in the Swiss lowlands. Oaks Quercus spp. were highly preferred and their diameter at breast height mainly ranged from 36-72 cm, corresponding […]

Factors affecting the occurrence of middle spotted and great spotted woodpeckers in deciduous forests ? a case study from Poland.

Middle Spotted Woodpecker (Dendrocopos medius) Science Article 1 abstract Based on published data on 117 deciduous forest sites studied in Poland, relationships between habitat factors (size of study plot, type and age of forest stands) and breeding of great spotted and middle spotted woodpeckers were examined. As compared with middle spotted woodpeckers, great spotted woodpeckers […]

EARLY BREEDING BEHAVIOR OF LINEATED WOODPECKERS

Lineated Woodpecker (Dryocopus lineatus) Science Article 1 abstract Lineated Woodpeckers (Dryocopus lineatus), widely distributed in Central and South America, resemble Pileated Woodpeckers (D. piZeatus) in many aspects of their breeding behavior. A purpose of the present study was to observe the courtship and related behavior of the neotropical species within this larger relationship (Mayr and […]

Variability of patch type preferences in relation to resource availabilityand breeding success in a bird

Lesser Spotted Woodpecker (Dendrocopos minor) Science Article 1 abstract This paper investigates how variability in partial foraging preferences for patch types can be used as a behavioral indicator of the energetic value of that patch type, and of overall food availability in the territory. The species studied was the lesser spotted woodpecker (Dendrocopos minor) and […]

Factors affecting the occurrence of middle spotted and great spotted woodpeckers in deciduous forests ? a case study from Poland.

Great Spotted Woodpecker (Dendrocopos major) Science Article 2 abstract Based on published data on 117 deciduous forest sites studied in Poland, relationships between habitat factors (size of study plot, type and age of forest stands) and breeding of great spotted and middle spotted woodpeckers were examined. As compared with middle spotted woodpeckers, great spotted woodpeckers […]

Continental Great Spotted Woodpeckers in mainland Britain-fact or fiction?

Great Spotted Woodpecker (Dendrocopos major) Science Article 4 abstract The wing lengths of Great Spotted Woodpeckers Dendrocopos major resident in Britain (subspecies anglicus) are more variable than had previously been realised, with one individual in a thousand reaching extremes of 123 mm and 140 mm. As a result, many of the past British records claiming […]

Nest-site selection and niche partitioning among the Great Spotted Woodpecker Dendrocopos major and Middle Spotted Woodpecker Dendrocopos medius in riverine forest of Central Europe

Great Spotted Woodpecker (Dendrocopos major) Science Article 3 abstract We studied nest-site selection of the Great- and Middle Spotted Woodpecker inhabiting the riverine forest remnants of Central Poland. In addition to nest tree characteristics and location in relation to edge proximity, a comparison between nesting and random sites within the woodpeckers’ territories allowed a study […]

The effect of forest patch size on the breeding biology of the great spotted woodpecker Dendrocopos major

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 […]
