Consistent behavioural differences among individuals are common in many
species and can have important effects on offspring fitness. To understand
such ‘personality’ variation, it is important to determine the mode of
inheritance, but this has been quantified for only a few species. Here, we
report results from a breeding experiment in captive zebra finches,
Taeniopygia guttata, in which we cross-fostered offspring to disentangle
the importance of genetic and non-genetic transmission of behaviour.
Genetic and foster-parents’ exploratory type was measured in a novel
environment pre-breeding and offspring exploratory type was assessed at
adulthood. Offspring exploratory type was predicted by the exploratory
behaviour of the foster but not the genetic parents, whereas offspring
size was predicted by genetic but not foster-parents’ size. Other aspects
of the social environment, such as rearing regime (uni- versus
biparental), hatching position, brood size or an individual's sex did
not influence offspring exploration. Our results therefore indicate that
non-genetic transmission of behaviour can play an important role in
shaping animal personality variation.
