Abstract
Flamingos (Phoenicopteridae) feed using a uniquely adapted bill that extracts small particles from the water and sediments. This study provides a detailed osteological description of the skull of the Chilean Flamingo (Phoenicopterus chilensis), with particular emphasis on feeding-related features. The skull exhibits a broad, flattened frontal region that articulates with an elongated upper jaw, which is deflected ventrally at approximately 45° and aligns seamlessly with the laterorostrally curved mandible, forming a configuration well suited for filter feeding. The mandible exhibits a low mechanical advantage, indicating an adaptation for rapid and repetitive movements rather than forceful biting. Jaw muscle attachment sites, including the fossa subtemporalis, fossa temporalis, and fossa ventralis palatini, are reduced, suggesting the presence of relatively small muscles that favor speed and precision.
期刊介绍：
The Journal of Morphology welcomes articles of original research in cytology, protozoology, embryology, and general morphology. Articles generally should not exceed 35 printed pages. Preliminary notices or articles of a purely descriptive morphological or taxonomic nature are not included. No paper which has already been published will be accepted, nor will simultaneous publications elsewhere be allowed.
The Journal of Morphology publishes research in functional, comparative, evolutionary and developmental morphology from vertebrates and invertebrates. Human and veterinary anatomy or paleontology are considered when an explicit connection to neontological animal morphology is presented, and the paper contains relevant information for the community of animal morphologists. Based on our long tradition, we continue to seek publishing the best papers in animal morphology.
