Data from: Perturbations highlight importance of social history in parakeet rank dynamics
<p>Dominance hierarchies can provide many benefits to individuals, such as access to resources or mates, depending on their ranks. In some species, rank can emerge as a product of a group's history of social interactions. However, it can be difficult to determine whether social history is critical to rank in observation-based studies. Here, we investigated rank dynamics in three captive groups of monk parakeets (<em>Myiopsitta monachus</em>). We used experimental social perturbations to test whether social history shapes rank emergence in these groups. Using targeted removals and reintroductions, we tested whether differently ranked individuals could re-take their ranks in hierarchies after reintroduction following their removal period from the group. We performed perturbations that consisted of an eight-day removal and an eight-day reintroduction period of 15 differently ranked focal birds. We found that no focal birds could regain their previous rank immediately following reintroduction and that the top-ranked birds showed greater relative rank loss than middle/low-ranked birds. We also found that morphology, specifically body weight, was unassociated with rank. Combined with previous results, this experiment supports the hypothesis that rank in monk parakeet dominance hierarchies is more likely to be an emergent outcome of past interactions and memory rather than based on individual characteristics. Gaining a better understanding of how individuals achieve and maintain rank can give insight into the role of cognition on rank acquisition, as rank position can have significant biological effects on individuals in hierarchically structured groups.</p>

Social association of monk parakeets in relation to proximity and relatedness
<p>Monk parakeets are social parrots that live in loose colonies, often building communal nests and breeding cooperatively. Relatives are clustered within nests and within colonies. Data was collected to test the hypothesis that social associations of monk parakeets when away from their nests (foraging, collecting nest material, etc) are driven by either the spatial proximity of their nests and/or by their relatedness. The dataset includes information on the identities of all birds that could potentially associate with a focal bird when away from their respective nests, an index of their association strength (calculated using the simple ratio index), the distance between their respective nests, the dyadic relatedness of the birds estimated using microsatellite genotypes, the number of times the two birds were seen together, and the total number of times the focal bird was observed. Data are separated into different files according to the year of data collection (2018 or 2019) to avoid pseudoreplication. Additional files exclude data from each year collected at a feeding station; these data files relate to a conservative anlaysis in case the supply of supplementary food affected social associations. An additional file contains data only for birds whose nests were in the same tree; this file was for an analysis of the effect of relatedness on social association while controlling for nest proximity. Finally, a file is also included that contains the 2018 as described above, but with dyads defined by sex (male-male, female-male or female-male). Each data file relates to a specific analysis in the paper. The conclusion is that monk parakeets do have specific social associations with conspecifics, and that these are infleuenced by nest proximity but not by genetic relatedness.</p>
Raw data for: Novel food resources and conservation of ecological interactions between the Andean Araucaria and the Austral parakeet
<p><span>In fragile ecosystems, the introduction of exotic species could alter some ecological processes. The Austral parakeet (<em>Enicognathus</em> <em>ferrugineous</em>) shows close ecological and evolutionary relationships with the Andean Araucaria (<em>Araucaria</em> <em>araucana</em>), so any alteration in these interactions may have negative consequences for both partners and for ecosystem functioning and structure. We conducted extensive roadside surveys to estimate the abundance of parakeets in the northern Patagonian Andes over four years and recorded the food plants consumed by foraging flocks. The use of native habitats and humanized areas like villages and farms was influenced by Araucaria seed crop. In masting years, the large seed crop allowed a massive use of this resource during the non-breeding season, and even during the breeding season. The exploitation of exotic plants was minor in the masting year, but became predominant in non-masting years, especially during the non-breeding season. This feeding switch towards exotic plants primarily arose because the low Araucaria seed crop in non-masting years is entirely consumed just after production by domestic and wild exotic mammals living in Araucaria forests year-round, thus forcing the displacement of parakeets towards anthropic habitats to exploit exotic plants. Given the degradation of the remaining Andean Araucaria forests due to the impact of exotic mammals on the ecological interaction between Araucaria and Austral parakeets, ambitious programs to exclude or reduce the density of these alien mammals, including livestock, are warranted. </span></p>
