Design of the cross-fostering experiment. Offspring from two nests (nests A and B) were swapped two days after hatching. They were raised thereafter by foster parents (parents A raised offspring B and vice versa). We expected that if the performance of the young was predicted by ornaments of the genetic mother, it would be indicative of genetic and/or pre-natal maternal effects. If the performance was linked to ornaments of the foster mother, it would be indicative of post-natal effects. The picture of the great tit by L.
