Résumé :	In 1998 a tree cavity nesting population of Swift (Apus apus) was rediscovered in the Spessart, an area of former occurrence. Potential breeding places of swift were mapped and showed a cavity density of 11 per ha. Over 75 % of all tree holes were located in the tree tops of 300 to 400 year old oak stands. A viable population of cavity nesting swifts and their bird community with Collared Flycatcher (Ficedula albicollis) and Middle Spotted Woodpecker (Dendrocopus medius) need extended old growth oak stands. A sustainable veener oak management in the Spessart region (Lower Franconia) secured survival of these species up to the present.
