Abstract
Flamingos are highly specialized filter-feeding birds with a uniquely adapted beak morphology, including a trough-shaped structure, a piston-like tongue, and comb-like lamellae that function similarly to baleen in whales. Despite this specialization, significant gaps remain in our understanding of flamingo beak evolution and development due to a limited fossil record and incomplete developmental data. The development of flamingo beak in living flamingos has never been published and the fossil record for flamingos has massive gaps in knowledge. Specifically, there are no transitional fossils showing the evolution of curved beaked, filter feeding specialist flamingos from the previously only known feeding ecology of straight beaked target feeding flamingos.
This study aims to characterize the development and functional maturation of the flamingo beak by documenting hatchling development in beak shape, curvature, and keratinous filter structures, along with behavioral milestones such as wading behavior, taping of the feet to remove food from sediment, putting their heads in the water, and filter feeding mimicry. To address the developmental component, I will collaborate with La Aurora Zoo in Guatemala, where measurements of hatchling beaks (specifically length, width, depth, and curvature) will be collected, alongside documentation of lamellae development and previously stated behavioral milestones. This data will be used to model developmental trajectories of both bony and keratinous structures and to assess the timing of functional maturation.
Additionally to studying living flamingos, this study will analyze fossil specimens of potential straight beak flamingos from the fossil record from museum collections in France (National Museum of Natural History in Paris and the Museum of Confluences in Lyon) to better characterize ancestral flamingo beak morphology.
By integrating developmental and fossil data, this study will provide new insight into the evolutionary origins and development of flamingo feeding adaptations.
Purpose
Flamingo biology and paleontology hold massive gaps in knowledge, both developmentally and in the fossil record. My research aims to close the knowledge gaps in their development and with this newfound knowledge, apply it to the missing history of their evolution.
Results
Currently we have not concluded our study and therefore do not have precise results.
Significance
This study holds significance as it has little to no publications on the topic, yet it could open doors to how biologists and paleontologists tackle challenges in multidisciplinary and creative ways. It also encourages international cooperation, bringing scientists together from all parts of the world. When the work is concluded, I will present at major science conferences like SVP and SAPE.
