| Résumé : | In spring 2007 a pair of Coal Tits reared a Eurasian Treecreeper alongside its own six young in the Black Forest (SW Germany). It is assumed that the egg had been laid by the female of a pair of Eurasian treecreepers, which had already started its brood in the same box. This is the first observed mixed brood involving a Eurasian Treecreeper and the first one between Coal Tit and a treecreeper. |
