Species richness, density, relative frequency of species, morphological similarity, foraging niche width and overlap measured on foraging sites of woodpecker and songbird communities were analysed in 2 original and 8 secondary Central European habitats in the Pilis UNESCO Biosphere Reserve and its vicinity c40 km from Budapest. The lowest species number and the highest extinction rate were in maize fields and small urban parks. The value of the average niche width is higher than that of the average niche overlap in original forest and large parks. The relationship between niche width and overlap is reversed in the secondary habitats except the large park. The foraging guilds are represented by few species and smaller values of morphological similarity in secondary habitats. In oak and locust-tree forests, when temperature is <0°C, and the soil is covered by snow, average niche width and overlap are lower than when temperature is >0°C, without snow. This situation is reversed in gardens and urban parks.
