White-backed Woodpecker (Dendrocopos leucotos) Science Article 1 abstract Body-mass and wing-length of adultWhite-backedWoodpeckers Dendrocopos leucotos were measured in 57 males and 55 females in Surnadal community in western Norway during November-June from 1985 to 2001. The mean physical condition (ratio bodymass : wing length) of reproducing females in coastal areas was better than of females […]

Breeding performance of the middle spotted woodpecker Dendrocopos medius in relation to weather and territory quality
Middle Spotted Woodpecker (Dendrocopos medius) Science Article 5 abstract Reproductive success in birds is influenced by a variety of factors, many of which can be attributed to human activities such as land use or forest management. Others like weather or age of the birds are not under human control but are influential as well. From […]
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
Middle Spotted Woodpecker (Dendrocopos medius) Science Article 2 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 […]
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 […]
Accuracy and efficiency of different techniques for censusing territorial Middle Spotted Woodpeckers Dendrocopos medius
Middle Spotted Woodpecker (Dendrocopos medius) Science Article 3 abstract The aim of the study was to test whether the methods using the playback technique produce accuratedata of population size when compared to the standard mapping and nest-searching methods. The three-visitmethod with audio-stimulation was found to produce data of the same accuracy (100%, n = 11 […]
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 […]

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 […]
