Résumé :	In the present paper we report about a pair of blue tits (Parus caeruleus) with a clutch of 19 eggs from which 17 young fledged. The nestlings were reared during the breeding season 2002 in a small-sized nestbox of a study area near Brunswick (52.16 N 10.32 E), Lower Saxony/Germany. Parentage analyses via multilocus DNA fingerprinting revealed that the feeding male and female were the genetic parents of 11 nestlings whereas the other 6 nestlings were unrelated to them. Possible causes for the production of the 19 egg-clutch are discussed.
