“…Even though they are one of the most familiar pet parrots and a common cagebird all around the world (since the end of the 18th century), they have not been much studied as biological models of avian cognition yet. To our knowledge, the only behavioral studies on cockatiels until now focused on reproductive behavior (Myers, Millam, Roudybush, & Grau, ; Millam, Roudybush, & Grau, ), egg productions (Millam, Zhang, & El Halawani, ), mate compatibility (Spoon, Millam, & Owings, , ; Yamamoto, Shields, Millam, Roudybush, & Grau, ) and flock social behaviors (Spoon et al, ; Seibert & Crowell‐Davis, ).…”

Food sharing and affiliation: An experimental and longitudinal study in cockatiels (Nymphicus hollandicus)

Food sharing has attracted much attention because of its apparently altruistic nature and its link to prosociality. However, food sharing has been mostly studied in a reproductive context, during courtship and parental care, where the fitness benefits are obvious. We still lack a clear understanding of the functions of food sharing outside any reproductive context and within social groups of same‐aged peers. Previous studies suggest that cofeeding, the action to let another animal feed from the same monopolizable food source, may be used to build and strengthen bonds between individuals. This may be particularly crucial in social birds forming long‐term associations between mates or siblings such as psittacids and corvids. Here, we investigated food sharing and affiliative behaviors such as allopreening in a psittacine species, namely in a group of captive juvenile cockatiels (Nymphicus hollandicus) consisting of five siblings and five unrelated birds. Our main objective was to study the developmental pattern of food sharing over time and its implication in social bonding depending on kinship, affiliation, and sex. Studying cockatiels in this context is providing many new information since most of the studies on food sharing in birds focused on corvids. We found that, contrary to jackdaws, cockatiels continued to share food with multiple individuals, although the frequency of cofeeding as well as the number of cofeeding partners decreased over time. Cockatiels shared more food with their siblings than with other conspecifics but they were not more likely to do cofeeding with birds of the opposite sex. We also found evidence that young cockatiels exchanged more food with those from whom they received food (reciprocity) and, to a lesser extent, allopreening (interchange), than from other cockatiels. Our findings suggest that in cockatiels, food sharing within social groups serves the formation (and maintenance) of affiliative bonds, especially between siblings, rather than pair bonds, but might additionally be explained by reciprocity, interchange, and harassment avoidance.

“…Saccopteryx bilineata typically reaches a total body length of about 7.5 cm (Yancey et al 1998). Voigt et al (2008) reported that day-roosting S. bilineata maintain a minimum social distance of 5-8 cm (indicating that body length may be a biologically relevant measure; see also Fleming et al 1998;Seibert and Crowell-Davis 2001;Richardson and Weckerly 2007), which informs the parameter used for measuring spatial difference in the present study. First, we measured social distance in body lengths between conspecifics in a colony using all possible combinations of individual bat pairs during scan-sampling.…”

“…the social distance, has been studied across several vertebrate taxa, including birds (Seibert and Crowell-Davis 2001), primates (Braune et al 2005;Mitani and Amsler 2003;ArroyoRodríguez et al 2006;Bezanson et al 2008), ungulates (Ruckstuhl and Neuhaus 2009;McDonnell and Murray 1995;Weeks et al 2000;Richardson and Weckerly 2007), pinnipeds (Mesnick and Le Boeuf 1991) and humans (Burgess 1983). Social distance studies have focused on signaling ecology (Braune et al 2005), mother-offspring behavior (Arroyo-Rodríguez et al 2006;Ruckstuhl and Neuhaus 2009), aggression (Weeks et al 2000;Seibert and Crowell-Davis 2001) or mating systems (Mesnick and Le Boeuf 1991;McDonnell and Murray 1995;Mitani and Amsler 2003;Bezanson et al 2008;Richardson and Weckerly 2007). While social organization has been studied in various bat species (reviewed in Bradbury 1977;McCracken and Wilkinson 2000), few studies have focused on the spatial association of individuals while roosting (Fleming et al 1998;Kerth and König 1999;Ortega and Maldonado 2006).…”

Understanding patterns and motivations for social spacing greatly illuminates the structure and internal dynamics of given groups or social systems. The highly social, polygynous greater sac-winged bat, Saccopteryx bilineata, represents an excellent model for social spacing analysis, since the choice of individual roost-sites within a day-roost constitutes an enduring, often repeated decision about relative proximity to conspecifics. Day-roost colonies consist of one or multiple harem groups, each with several females and a single male. Additionally, non-harem males without females may be present. A social-distancetime-budget metric revealed that harem males, females, and non-harem males differed significantly in their respective spatial associations while roosting. Harem males and females were most closely associated, with harem males located at the center of harems instead of at the borders. Non-harem males associated significantly closer with one another than with harem females that they were trying to access. The signaling modality mediating social interactions depended on the respective social distances between communicating bats. Our results suggest a concentric social organization based around harem males, which may select roost sites in closest possible proximity to females to enhance courtship signal strength. This constitutes an interesting deviation from the normative form of harem maintenance, patrolling borders, in mammals.

“…Dominance L'existence d'individus dominants et dominés chez les perroquets est bien établie, mais sa signification chez les psittacidés de compagnie fait l'objet de débats 8,10,20,28,34,35,38,40 . La dominance est généralement corrélée à l'augmentation du comportement d'exploration chez les jeunes et à l'augmentation de l'agressivité chez les adultes.…”
