Precocial development has the advantage of reducing the time spent in incubating the nestlings as the chicks are born with a covering of down. There is only contradictory information on the social system of closely related Japanese quail (C. japonica) in the wild [189], but the closest relative of the hybridised Bengalese finch, the white-rumped munia (L. striata), is social.

Garnett ST. Natural conflict resolution. As there is only a very limited number of studies available that specifically incorporate the developmental mode in questions pertaining to complex sociality, and because social complexity is difficult to comparably quantify (but see [42] for a recent review and new definition), we were unable to perform a rigid meta-analysis. 2010;176:E339.

We aim to assess whether the inferred indirect link of a relationship between developmental mode and social complexity via variation in relative brain size is supported or if there is a direct link between developmental mode and social complexity independent of brain size variations (Fig. Advantages from Time Zone Differences. Oxytocin is also known for its positive impact on the development of trust and recognition of familiar individuals in rodents [68] and estrildid finches [61]. It is described best by the maintenance of individualized long-term, mutual, dyadic valuable relationships (sensu [71]). Acta Ethologica. 2005;93:1639.

Once again, there is an ongoing debate as to whether the ability to recognise others is cognitively demanding, as it can either be achieved through cognitively simpler means, such as differentiating between more or less familiar individuals (class level recognition ([148], but see [149]), or through recognition of unique individual features (true individual recognition), which is thought to require specific cognitive adaptations [150]. In contrast, cooperative breeding in mammals is generally rare (<5% species; [125]) and where it does occur, cooperative breeding appears to be independent of the developmental mode [125]. Google Scholar. However, the view that complex social interactions indeed require a large brain has recently been challenged [1, 7, 16, 21, 46], which may imply that the relationship between social complexity and developmental mode is less clear as well (see Fig. Cooperative breeding by buff-throated partridge Tetraophasis szychenyii: a case in the Galliformes. Dugatkin LA. One often-neglected feature that may underlie variation in the complexity of social systems is a differentiation of species with respect to their developmental mode, i.e. Group living in the black-breasted wood-quail and the use of playbacks as a survey technique.

One of our aims here is to survey the existing literature to determine whether social complexity is related to variation in developmental mode in mammals and birds, the two most extensively studied vertebrate taxa in this regard. 2010;79:105566. 2011;108:616974.

The social organisation of the dusky moorhen, Gallinula tenebrosa Gould (Aves: Rallidae). Nature. Valuable relationships may occur among pair partners, direct family members or distantly related kin [86, 97, 98] as well as between unrelated individuals [71, 99] and may involve coalition and alliance formation [100, 101], communal defence [102, 103], communal or cooperative breeding [98, 104110], conflict resolution [74, 111115], and social support ([116, 117] and references therein) (see Table1 for a complete overview).

The result of the above-mentioned experiment might be a consequence of cognitive skills that are related to sociality, rather than the developmental mode, as, for example, highly social greylag geese (Anser anser) memorise dyadic relationships in a hierarchical colour series for approximately one year [187].
