Difference on cone size preferences between two coniferous species by Great Spotted Woodpecker (Dendrocopos major)
The number of species that specialize in pre-dispersal seed predation is relatively small. Examples of specialized pre-dispersal seed predators adapted to feeding on closed cones include vertebrate species like Crossbills, Squirrels, Nutcrackers and Woodpeckers. Seed predation selects against certain phenotypic features of cones and favors another phenotypic features. In this study, we document...
متن کاملThe carotenoid-based red cap of the Middle Spotted Woodpecker Dendrocopos medius reflects individual quality and territory size
Carotenoid-based plumage ornaments have the potential to signal individual condition and health in many species of birds. However, very little is known about the function of red plumage in woodpeckers. We assessed whether the red cap displayed by both male and female Middle Spotted Woodpeckers reflects individual quality, finding that the size of the cap is sex-dependent, whereas the brightness...
متن کاملhabitat evaluation of middle spotted woodpecker (dendrocopos medius) in golestan national park
the evaluation of ecological characteristics of wildlife species has fundamental role in species management, because taking a decision for proper method of management is only possible by characterizing of ecological requirements of a species. in this study, suitable habitat of middle spotted woodpecker was investigated in golestan national park. presence and absence of birds and environmental v...
متن کاملLogging affects the white-backed woodpecker Dendrocopos leucotos distribution in the Białowieża Forest
The white-backed woodpecker (WbW) is a critically endangered species in Europe. The Białowieża Forest (BF) is of major importance for its conservation. Distribution of WbW in deciduous stands of the BF was studied in relation to habitat resources. In March–April 2005 we replicated a 1991 study where the WbW population was estimated using playback drumming techniques. Woodpeckers were recorded i...
متن کاملGreat spotted woodpeckers Dendrocopos major exert multiple forms of phenotypic selection on Scots pine Pinus sylvestris
Relatively few animal species extract seeds from closed conifer cones because of the forces required to spread apart or penetrate the woody scales. Those species that forage on seeds in closed cones tend to forage selectively, and therefore act as selective agents on cone structure. However, little is known about the foraging preferences and thus phenotypic selection that is exerted on conifers...
