Eksempler på woodpecker

• Availability of nesting sites as a limit to woodpecker populations.

• The absence or scarcity of large, snag-foraging woodpeckers from older logged stands suggests that this resource may remain in low abundance for a considerable time.

• Results from woodpecker surveys revealed an atypical response to logging.

• The other birds get the water, and ever since then the woodpecker has been pecking at things.

• However, these studies lacked sufficient data to identify the most affected woodpecker species.

• The woodpecker community may be affected by the reduction in forest structural complexity that results from silvicultural treatments and may persist throughout the logging cycle.

• Although total woodpecker abundance differed only slightly between forest types, relative abundance of certain species differed significantly.

• This study investigated the community of woodpeckers in a forest that was selectively logged 40 y ago compared to the community in adjacent unlogged forest.

• Five visitors were unidentified passerines; the sixth was an unidentified woodpecker.

• The goal of this study was to document possible changes in the woodpecker community by identifying differences in relative abundance of individual species.

• A significant difference in the overall woodpecker community between the two forest types was found.

• The availability of suitable microhabitat corresponded strongly with woodpecker abundance, and snags were the most highly preferred foraging substrate across species and study sites.

• These novel resources may explain, in part, the maintenance of high woodpecker diversity in tropical rain forests.

• Inbreeding depression and its effects on natal dispersal in red-cockaded woodpeckers.

• The strong preference for snags in all forest types supports the suggestion that snags are important in determining the abundance of woodpeckers.
