Abstract

ABSTRACT Capsule Although the Great Spotted Woodpecker Dendrocopos major and Grey-headed Woodpecker Picus canus have overlapping ranges in South Korea, they occur in areas with different forest structures and the occurrence of each species is associated with their main foods. Aims To investigate the biotic factors related to the occurrence of the Great Spotted Woodpecker and the Grey-headed Woodpecker, two species that frequently inhabit overlapping regions in South Korea. Methods Correlations between the occurrence of the two woodpecker species, forest characteristics, and bird and insect species richness were evaluated based on large-scale public data from the National Ecosystem Survey and a Forest Type Map. Results The occurrence of Great Spotted Woodpeckers was associated with forest stands with at least 75% coniferous trees, whereas the occurrence of Grey-headed Woodpeckers was negatively associated with forested areas with canopy cover exceeding 50%. The occurrence of both species was strongly and positively correlated with the species richness of forest birds. The occurrence of Great Spotted Woodpeckers was correlated with the species richness of Coleoptera, while that of the Grey-headed Woodpecker was correlated with the species richness of Hymenoptera and Diptera. Conclusion The co-occurrence of the two woodpecker species within shared habitats can be explained by low competition due to differences in preferred forest characteristics and in the food sources used by each species.

韩国森林特征、鸟类和昆虫多样性对大斑啄木鸟和灰头啄木鸟发生的影响

虽然大斑点啄木鸟(Dendrocopos major)和灰头啄木鸟(Picus canus)在韩国有重叠的分布范围，但它们分布在不同的森林结构地区，而且每种物种的出现都与它们的主要食物有关。目的研究大斑点啄木鸟和灰头啄木鸟这两种经常栖息在韩国重叠地区的物种发生的生物因素。方法利用全国生态系统调查的大规模公开数据和森林类型图，评价两种啄木鸟的发生与森林特征、鸟类和昆虫物种丰富度之间的相关性。结果大斑啄木鸟的发生与针叶树≥75%的林分呈负相关，而灰头啄木鸟的发生与冠层盖度超过50%的林分呈负相关。这两个物种的发生与森林鸟类物种丰富度呈显著正相关。大斑啄木鸟的发生与鞘翅目物种丰富度相关，而灰头啄木鸟的发生与膜翅目和双翅目物种丰富度相关。结论两种啄木鸟在同一生境内共存的原因可能是由于两种啄木鸟偏好的森林特征和食物来源的差异导致竞争较低。

期刊介绍： Bird Study publishes high quality papers relevant to the sphere of interest of the British Trust for Ornithology: broadly defined as field ornithology; especially when related to evidence-based bird conservation. Papers are especially welcome on: patterns of distribution and abundance, movements, habitat preferences, developing field census methods, ringing and other techniques for marking and tracking birds. Bird Study concentrates on birds that occur in the Western Palearctic. This includes research on their biology outside of the Western Palearctic, for example on wintering grounds in Africa. Bird Study also welcomes papers from any part of the world if they are of general interest to the broad areas of investigation outlined above. Bird Study publishes the following types of articles: -Original research papers of any length -Short original research papers (less than 2500 words in length) -Scientific reviews -Forum articles covering general ornithological issues, including non-scientific ones -Short feedback articles that make scientific criticisms of papers published recently in the Journal.
