“…One possible scenario is that the parental motivation for brooding is governed by a fixed time program and decreases steadily after hatching. However, in disagreement with this hypothesis of a fixed time program for brooding are the observations of Richard- & Leboucher (1987) in the domestic fowl Gallus domesticus. They found that substituting old chicks with younger ones led immediately to the appropriate maternal brooding response.…”

Time budgets of free-living chicks of Arctic Terns Sterna paradisaea and Common Terns S. hirundo throughout development are presented with special reference to changes in time allocation when growth rate varies. Chicks of both species were inactive most of the time observed (87%). Time allocated to the different behaviours changed during development and was generally better correlated with body mass than age. Slower growing nestlings were brooded more and allocated more time to quiescence and less time to locomotion, preening, begging and attacking (the latter two significant only for the Arctic Tern). The energetic implications of variation in time budgets with age and growth rate were considered. Parental brooding resulted in an average energy saving of nearly 40% of an individual nestling's thermoregulatory costs. Whereas thermoregulatory costs remained nearly unchanged in Arctic Tern chicks, these were negatively correlated with growth rate in Common Terns. Tentatively, we estimated a 30% reduction in a nestling's total energy requirement for a 50% reduction in average growth rate for both species.

“…In our experiment, flocks of chicks met the robot only 36 h after hatching; hence, conditions for an unconditional attachment were probably not met. However, as late filial attachment of chicks has been reported (Vidal 1976, Richard-Yris andLeboucher 1987b), the question of attachment deserves discussion, especially if robot movement can have a role in this issue (Ten Cate 1986, 1989.…”

Influence of a mobile robot on the spatial behaviour of quail chicks

et al. 2011

Quail chicks encountered an autonomous mobile robot during their early development. The robot incorporated a heat source that stimulated following of chicks. The spatial behaviour of grown-up chicks was tested in an exploration test and a detour test. Chicks that grew with the mobile robot exhibited better spatial abilities than chicks grown with a static heat source. We discuss these results in the perspective of animal-robot interaction and of the role of early spatial experience on the behavioural development.
