Résumé :	A wood-park of deciduous type (c. 27 ha) was censused 1985-2004 among others for territories of Great Spotted Woodpecker Picoides major including searches for cavities containing broods. On average, 16.5 +/- 1.6 territories (6.2 terr/10 ha) were found without any trend, from which 77% were confirmed by cavities with broods. Trees containing such cavities were not evenly distributed over all existing species of trees. However, neophytes such as Read Oak Quercus rubra, Robinia pseudacacia and Black Cherry Prunus serotina were strongly favoured, possibly because of signs of high damages of these tree species. Repeated use of cavities was only little documented. A great number of Starlings Sturnus vulgaris occurred as users of cavities of Great Spotted Woodpecker and confirmed a high amount of existing cavities. Green Woodpecker Picus viridis, Middle Spotted Woodpecker Picoides medius and Lesser Spotted Woodpecker Picoides minor were also breeding in the study area.
