“…However, fine-scale genetic structure can be an intrinsic feature evolving in particular species 23 , 24 , as promoted by socio-cultural forces driving pairing, dispersal and group cohesion even in large and widely distributed populations of social species 8 , 25 . A comprehensive evaluation of these traits is paramount to understanding the structure and functioning of metapopulations and for adequate conservation management, including captive breeding and reintroduction of threatened species 26 , 27 .…”

Behavioural and socio-cultural traits are recognized in the restriction of gene flow in species with high cognitive capacity and complex societies. This isolation by social barriers has been generally overlooked in threatened species by assuming disrupted gene flow due to population fragmentation and decline. We examine the genetic structure and ecology of the global population of the Critically Endangered red-fronted macaw (Ara rubrogenys), an endemic species to the inter-Andean valleys of Bolivia. We found a fine-scale genetic structuring in four genetic clusters. Genetic diversity was higher in wild compared to captive-bred macaws, but similar to that of captive wild-caught macaws. We found no clear evidence of severe genetic erosion in the population in recent decades, but it was patent in historic times, overlapping with drastic human habitat transformation and macaw persecution over millennia. We found no evidence of geographical and ecological barriers, owing to the high dispersal ability, nesting and foraging habits between genetic clusters. The lack of genetic intermixing despite long-distance foraging and seasonal movements suggests recruitment in natal colonies and other social factors reinforcing philopatry-related genetic structure. Conservation efforts should be specifically focussed on major threats in each genetic cluster as independent conservation units, and also considered in ex-situ management.

“…Many parrot species, including the monk parakeet, are either intruded upon by development in their native ranges or released into novel environments through human intervention (Russello, 2008;Strubbe & Matthysen, 2009;Peck et al, 2014;Lopes et al, 2017). In such species, coping with novel challenges such as food-finding, which is often dependent on more extreme risk taking behaviours (Martin & Fitzgerald, 2005;Short & Petren, 2008;Lapiedra et al, 2017), can be strongly tied to personality expression in a social unit (Aplin et al, 2014).…”

The standard approach for characterizing boldness rarely considers the influence of social environment on the expression of boldness in group-living animals. We studied a wild-caught, captive population of monk parakeets (Myiopsitta monachus) to investigate the impact of conspecific presence on boldness -a personality trait in monk parakeets -in a controlled environment. We quantified seven boldness metrics across three types of behavioural assay: novel object, emergence, and predator exposure tests in the presence of a companion pair of flock mates. Because of the high degree of sociality in this species, we hypothesized that the presence of companion birds would facilitate the focal individuals' behavioural responses (i.e., increase the average boldness level). We found that behavioural response in a risky foraging context was inversely correlated between solitary and social condition in males, but not in females. Our results have implications for characterizing sex-specific differences of risk-taking behaviour in social animals.

“…In general, the sex variable is not taken into account in conservation programs, although it is a factor that exerts influence on stress, dispersion, reproduction and transportation (Lopes et al 2017). As well as in this study, behavioral differences between sexes have been reported in the Greater Rhea either in captivity (Sales et al 2000, Della Costa et al 2013, as in the wild (Reboreda & Fernández 1997, Carro & Fernández 2009, but still a relationship could not be established among sex, the application of antipredator training, and survival (Vera Cortez et al 2015).…”
