“…A single metapopulation was identified across the range of the Chilean Flamingo, harboring minimal genetic variation. This finding parallels similar recent findings in other widespread flamingo species [ 18 , 19 ] and is consistent with the appearance of opportunistic breeding [ 25 ] and a nomadic lifestyle [ 26 ] in all flamingos. Given these results, minimal genetic structure is expected for the phylogeographically unstudied Andean, James’s and American Flamingos.…”

BackgroundModern flamingos (Phoenicopteridae) occupy a highly specialized ecology unique among birds and represent a potentially powerful model system for informing the mechanisms by which a lineage of birds adapts and radiates. However, despite a rich fossil record and well-studied feeding morphology, molecular investigations of the evolutionary progression among modern flamingos have been limited. Here, using three mitochondrial (mtDNA) markers, we present the first DNA sequence-based study of population genetic variation in the widely distributed Chilean Flamingo and, using two mtDNA and 10 nuclear (nDNA) markers, recover the species tree and divergence time estimates for the six extant species of flamingos. Phylogenetic analyses include likelihood and Bayesian frameworks and account for potential gene tree discordance. Analyses of divergence times are fossil calibrated at the divergence of Mirandornithes (flamingos + grebes) and the divergence of crown grebes.ResultsmtDNA sequences confirmed the presence of a single metapopulation represented by two minimally varying mtDNA barcodes in Chilean flamingos. Likelihood and Bayesian methods recovered identical phylogenies with flamingos falling into shallow-keeled (comprising the Greater, American and Chilean Flamingos) and deep-keeled (comprising the Lesser, Andean and James’s Flamingos) sub-clades. The initial divergence among flamingos occurred at or shortly after the Mio-Pliocene boundary (6–3 Ma) followed by quick consecutive divergences throughout the Plio-Pleistocene. There is significant incongruence between the ages recovered by the mtDNA and nDNA datasets, likely due to mutational saturation occurring in the mtDNA loci.ConclusionThe finding of a single metapopulation in the widespread Chilean Flamingo confirms similar findings in other widespread flamingo species. The robust species phylogeny is congruent with previous classifications of flamingos based on feeding morphology. Modern phoenicopterids likely originated in the New World with each sub-clade dispersing across the Atlantic at least once. Our divergence time estimates place flamingos among the youngest families of birds, counter to the classical notion of flamingos as among the oldest based on biogeography and the fossil record. Finally, we designate ‘Phoeniconaias’ as a junior synonym of ‘Phoenicoparrus’ and redefine the latter genus as containing all flamingos more closely related to Phoenicoparrus andinus than Phoenicopterus roseus.

“…Taking into account that lowland lakes in Argentina are key habitats for vulnerable species of flamingoes all the year round (Bucher and Curto, 2012) or especially during winter when some of the high-Andes lakes in Argentina, Bolivia, Chile and Perú freeze (Caziani et al, 2007), further research on zooplankton is needed. They would be a tool for monitoring the ecological quality of the wetlands related to the conservation biology of flamingoes, particularly for P. chilensis, the most abundant species, wich can use zooplankters as a food source.…”

“…In the wild, flamingos often breed in huge flocks numbering thousands and even tens of thousands of individuals, but breeding in much smaller flocks of just tens of birds also occurs (Sprunt, ) and small flocks of birds in captivity can also reproduce if provided with the right conditions (Pickering et al ., ). Wild flamingo flocks breed erratically, sometimes going years without any success; this is often the result of environmental conditions, such as seasonal shifts in patterns of temperature and rainfall (Bucher, ; Vargas et al ., ; Bucher & Curto, ), that disrupt, delay or prevent breeding from occurring. Similar problems associated with these climatic variables can affect flocks in zoological institutions (Pickering et al ., ; Pickering, 1992b; Stevens & Pickett, ; Studer‐Thiersch, 2000b).…”

Flamingos are ubiquitous captive species (potentially the world's most commonly kept zoo bird) that have long lifespans and unique breeding cycles. In‐depth research into the links between provision (enclosure, husbandry), behavioural performance (reflecting internal motivation) and perceived welfare state (from behavioural cues) can inform management for good welfare over the many decades of a bird's life, and benefit reproductive output. Here, the published literature on flamingo husbandry is reviewed, with reference to our current understanding of flamingo behaviour in the wild. Evaluation of whole‐flock time budgets and assessment of behavioural diversity can highlight any deviation from a norm. Several published works suggest ways of improving breeding success in captive flamingos by re‐evaluating husbandry routines as well as highlighting minimum numbers of birds per flock for ‘good welfare’. Research has shown that some aspects of zoo‐flamingo activity can match that of wild birds. Further examination of specific behaviour patterns, as well as the motivations for these, would allow for evidence‐based enclosure design and provision of species‐specific behavioural husbandry. Future research topics covering social support, foraging activity and developing a definition of ‘positive welfare activity’ would further enhance zoo management practices for these birds.
