0 a bird that uses its strong beak to make holes in tree trunks in order to find insects to eat -- 啄木鳥
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.
