“…An original procedure of maternal behaviour induction developed specifically for gallinaceous species [17] facilitates experimental control of the influence of genetic and non-genetic factors. Finally, the emotional traits of Japanese quail are determined partly by genetic factors [18], as well as by early maternal influence [19], [20].…”

The development of fearfulness and the capacity of animals to cope with stressful events are particularly sensitive to early experience with mothers in a wide range of species. However, intrinsic characteristics of young animals can modulate maternal influence. This study evaluated the effect of intrinsic fearfulness on non-genetic maternal influence. Quail chicks, divergently selected for either higher (LTI) or lower fearfulness (STI) and from a control line (C), were cross-fostered by LTI or STI mothers. Behavioural tests estimated the chicks' emotional profiles after separation from the mother. Whatever their genotype, the fearfulness of chicks adopted by LTI mothers was higher than that of chicks adopted by STI mothers. However, genetic background affected the strength of maternal effects: the least emotional chicks (STI) were the least affected by early experience with mothers. We demonstrated that young animal's intrinsic fearfulness affects strongly their sensitivity to non-genetic maternal influences. A young animal's behavioural characteristics play a fundamental role in its own behavioural development processes.

“…By comparing behavioral characteristics of Japanese quail chicks reared in complete maternal deprivation and those of chicks adopted by foster mothers, several authors illustrated the fundamental role of mothers on behavioral ontogeny. They have evidenced maternal influence on a range of behaviors (Bertin and Richard‐Yris, ; De Margerie et al, ; Pittet et al, in press), including fearfulness (Bertin and Richard‐Yris, ; Richard‐Yris et al, ) and sociality (Bertin and Richard‐Yris, ; Formanek et al, ). Consequently, we hypothesized that quail mothers influenced the emergence of sex differences.…”

Precocial bird mothers shape sex differences in the behavior of their chicks

Compared to mammals and altricial birds, evaluations of differences related to precocial birds' sex have often been limited to sexual behavior. Nevertheless, the extensive use of precocial bird models for investigating behavioral development issues requires in depth knowledge concerning the emergence of sex differences. Here, we evaluated behavioral differences between Japanese quail chicks in relation to their sex. We know that maternal influences are strong and early social environment shapes behavioral development in this species. Therefore, we investigated the emergence of sex differences in two very different early social situations to evaluate the impact of precocial bird mothers on sex differences. We assessed behavioral differences related to sex of (1) non-brooded chicks and of (2) brooded chicks, using various ethological tests to evaluate emotional reactivity and social motivation differences related to sex. Our results show that both non-brooded and brooded chicks present behavioral differences related to sex. They differed greatly according to chicks' early experience. Sex-related differences between maternally deprived (non-brooded) chicks concerned mainly fearfulness, whereas differences between male and female brooded chicks concerned mainly their reactions to social isolation. We hypothesize that mothers attenuate sex differences related to fearfulness by being a model for responses to fear-eliciting situations and by providing a similar secure basis to both males and females. We finally propose that mothers induce differences in chicks' sociality by providing asymmetrical care toward males and females.

“…This social isolation prevented subjects from learning each other; they were especially deprived of the chance to learn from their experienced parents. Animals raised without parents may show a variety of severe deficits in social interactions (Bertin and Richard-Yris, 2005) and a reduced ability for social learning (Lévy et al, 2003). Therefore, the lack of social experience in hand reared juveniles might result in poor hoarding behavior, although we did not test this directly.…”

Differences in hoarding behavior between captive and wild sympatric rodent species

In hand reared birds and mammals, it is generally considered that the development of hoarding behavior is the result of an interaction between the development and maturation of the nervous system and learning from individual experience. However, few studies have been done on wild animals. We tested differences in hoarding behavior between captive reared and wild individuals of two sympatric small rodents, Korean field mice Apodemus peninsulae and Chinese white-bellied rats Niviventer confucianus. Our aim was to identify if lack of experience from the wild would result in poorly developed hoarding behavior. The Korean field mice perform scatter-and larder-hoarding behaviors whereas Chinese white-bellied rats hoard food in larders only. Within outdoor enclosures we compared seed-hoarding behavior in reared juveniles (RJ, 40-50 d old, pregnant mothers were captured in the wild), wild juveniles (WJ, as young as the RJ) and wild adults (WA, over-winter animals). We found that a lack of experience from the wild had significant effects on seed-hoarding behavior for both species. The RJ-group removed and hoarded fewer seeds than the WJ-and WA-groups. The two latter groups hoarded seeds in a similar way. In the Korean filed mouse the RJ-group placed more seeds on the ground surface than other groups. These findings suggest that wild experience is important for the acquisition of an appropriate food-hoarding behavior (especially for scatter-hoarding) in these species [Current Zoology 57 (6): 725-730, 2011].
