T2  - BWP update
N2  - The Great Spotted Woodpecker is the most common and best-known woodpecker species in the W Palearctic. The sections Habitat, Distribution, Population, Movements, Food, Social pattern and behaviour, Voice, Breeding, Plumages, Bare parts, Moults, Measurements, Weights, and Geographical variation have been updated or completely rewritten, and a new section has been added on Conservation. High flexibility enables the Great Spotted Woodpecker to utilize a great variety of habitats, from Arctic taiga through boreal and temperate to Mediterranean (N Africa and Canary Islands) and Alpine forest zones, wherever there are mature trees of any sort with sufficient growth to accommodate nest-holes and with a supply of available food. The Distribution and Population sections include new data of population tendencies, with stable or positive trends in most European countries and fluctuating populations in N Europe. Recent negative range trends with small decreases only in S Europe, apparently due to loss of wooded habitats. The Conservation section presents literature on the Great Spotted Woodpecker as the key or umbrella species for secondary cavity-nesting species. This section also demonstrates the importance of woodpeckers as indicators for naturally dynamic forests with tree species diversity, forest management, and sustainable forestry. Woodpeckers can be part of a monitoring system of e.g. sustainable forestry, but species from other organism groups are also required. The section on Movements has been updated with new data on dispersal and summer/autumn and spring migration. The Great Spotted Woodpecker uses a very wide and varied diet and is characterized as a 'universalist' in food-gathering; pecking and hammering are most important in autumn and winter, gleaning and probing are important at times of high food availability at the tree surface in spring and summer. It takes arthropods and insect larvae, coniferous seeds and various nuts mainly in autumn and winter, and drills holes for sap-sucking in spring, takes surface dwelling arthropods and caterpillars, bird eggs and nestlings, and fruits and berries in spring and summer. The Social pattern and behaviour section presents new data on the mating system, parental effort, pair-bond, divorce rate, survival rate, and mortality. Great Spotted Woodpeckers are socially and genetically monogamous with a potential to polyandry, which was recorded in Japan. Changes of partner between seasons common. Males usually invest more in nesthole construction and guarding than the females and contribute the same amount or more to brood care. Males usually incubate and brood at night, as with all studied woodpeckers, and defend territories, which seem to be important for female choice. Females compete intensely for access to males and perform male-like courtship behaviours such as drumming. Great Spotted Woodpeckers are intelligent and currently doing damage to house facades. The Voice section presents mainly new data on calls and instrumental signals of the young. The Breeding section has been updated with new information about nest-sites, breeding behaviour, and breeding success. New data on age determination are shown in the Bare parts and Moults sections. Additional data are provided on size and weight.
