“…Genetic variation for the rate of 'peeping' by chicks has been suggested for White Leghorn-like commercial stocks, in experiments using a paternal half-sibling breeding design (two hens artificially inseminated by the sperm of one rooster per replicate). While significant between-dam variation was found, the between-sire component of variance was not significant (Webster & Hurnik 1987; Table 1). The authors explained this discrepancy either by maternal effects, or the lower genetic variation among roosters than among hens.…”

“…The precocial young of chickens, Gallus gallus domesticus, emit 'peep' vocalizations, and mainly do so when the hen is absent (Bermant 1963). 'Peeping' may thus reflect the chick's solicitation for proximity of the mother (Webster & Hurnik 1987).

“…Covariation between the phenotypic expressions of offspring begging and parental provisioning may also reflect an underlying genetic correlation (Wolf & Brodie 1998). A prerequisite for a genetic correlation between behaviours is the behavioural variation to be heritable, which has already been shown for both begging and provisioning (Webster & Hurnik 1987;Freeman-Gallant 1999;MacColl & Hatchwell 2003;Dor & Lotem 2009, 2010Kim et al 2011;Estramil, Eens & M€ uller 2014). However, studies on genetic correlations between mean levels of behaviour are rare (but see Hager & Johnstone 2003 for an exceptional study on mice) and as yet have not been conducted for behavioural reaction norms.…”

Within‐family parent–offspring co‐adaptation in a wild bird: on static traits, behavioural reaction norms, and sex differences

Summary Parental care, a central component of reproduction in a wide range of animal species, often involves elaborate behavioural interactions between parents and their offspring. Due to the reciprocal nature of these interactions, it has been hypothesized that parental and offspring behaviours (e.g. parental food provisioning and offspring begging) are not only target but also agent of selection. These traits are therefore expected to co‐evolve, ultimately leading to co‐adaptation of parent and offspring behaviours within families. However, empirical data on such parent–offspring co‐adaptation are limited, particularly for wild populations. Furthermore, mean levels of behaviour (as measured in previous studies) may not adequately describe the dynamic nature of the reciprocal interplay between parents and their offspring, and instead rather the behavioural reaction norms for provisioning and begging may be co‐adapted. We applied a large‐scale cross‐fostering study over 3 consecutive breeding seasons to investigate whether provisioning behaviour of wild blue tit (Cyanistes caeruleus) parents covaries with the begging behaviour of their genetic, cross‐fostered offspring. We simultaneously analysed parent and offspring behaviours, both as static traits (mean levels) and behavioural reaction norms (offspring begging as a function of food deprivation and parental provisioning as a function of short‐term experimental changes in brood size). Neither maternal nor paternal provisioning rates covaried with the begging intensity of their genetic offspring when analysed as mean levels of behaviour. However, the slopes of the reaction norms for provisioning and begging were negatively correlated between male, but not female, parents and their genetic offspring. Thus, fathers that change their provisioning rate strongly with brood size sire offspring whose level of begging only weakly increases with hunger, and vice versa. The observed covariation suggests the existence of sex‐specific optima for parent–offspring trait combinations. Thus, our study not only highlights the importance of a behavioural reaction norm approach when investigating parent–offspring interactions, but also stresses the relevance of considering parents as separate units, at least for biparental species.

“…As 2-day-old chicks, the same birds and their siblings were tested for peeping in an environment without mirrors and then with mirrors (Webster and Hurnik, 1987). Chicks derived from male parental Stock 1 had higher levels of peeping in the absence of mirrors.…”

Open field tests were carried out using 17-wk-old pullets derived from two commercial White Leghorn type stocks of males bred to White Leghorn type females from a stock kept at the University of Guelph. Behavioural differences both between and within stocks were investigated, and the heritabilities of the behavioral variables were calculated. The offspring of male parental Stock 1 took longer to manifest pecking behavior than those of male parental Stock 2, and also made less use of the areas of the open field farthest from the starting point. Male parental Stock 1 showed significant variability due to sires for sitting and standing behavior, whereas for male parental Stock 2, variability existed for neck extension and the number of behavioral states manifested. Significant variability due to dams was apparent for several behavioral variables. Heritability estimates ranged from zero to quite high, with those corresponding to the significant sire effects being the highest. The results suggest that the offspring of male parental Stock 2 were the more responsive to social stimuli and were possibly more investigative. Significant sire and dam effects indicate that there are differences in the way individual chickens respond to novel environments, and that these responses may be modifiable through selection.
