“…The food preferences of the greater rhea in the wild (Martella et al, 1996) suggest that no fundamentally different feeding behaviours are required, other than the ones analysed in our study. The diet consists of a wide variety of food items, but is mainly vegetarian (Mosa, 1993;Martella et al, 1996;Quin, 1996). The assumption that the feeding behaviour is characteristic for all Palaeognathae is confimed by a number of observations.…”

Cranial kinesis is an important feature in avian feeding behaviour and involves the transmission of quadrate movement to the upper bill by the Pterygoid-Palatinum Complex (PPC). The PPC in Palaeognathae is remarkably different from that found in Neognathae. In this study we analyse whether the special morphology of the PPC is an adaptation to the feeding behaviour of the Palaeognathae. Behavioural analyses of the rhea Rhea americana showed that the feeding behaviour of the rhea is typical 'Catch and Throw' behaviour, independent of the size of the food item. Drinking is achieved by a scooping movement followed by a low-amplitude tip-up phase. During feeding rhynchokinetic movements of the upper bill were observed. However, cranial kinesis was limited and may differ from rhynchokinesis in neognathes as a clear bending zone seemed absent. Since the movement patterns are considered very similar to the basic feeding behaviour in neognathous birds it is concluded that the specific morphology of the PPC is not the result of specific functional demands from palaeognathous feeding behaviour.

La investigación se realizó entre los meses de mayo a diciembre del 2011, en el cerro Quenacoto de la comunidad Cayachira, Puno. Los objetivos fueron: (1) Estimar el tamaño poblacional, (2) Caracterizar el hábitat y (3) Determinar la dieta de T. pentlandii en la comunidad de Cayachira. Para estimar el tamaño poblacional se aplicó el método indirecto de búsqueda intensiva, en el que se registró y recolectó huellas, fecas, plumas, cantos de la especie. Cada indicio fue georeferenciado con un GPS Garmin HC. Se hizo muestreos aleatorios con cuadrantes de 1m de lado para determinar la diversidad y riqueza de especies del hábitat en el programa Krebs. Se tomó muestras del agua y suelo del hábitat para luego analizarlas en el laboratorio de la UNA Puno. La temperatura ambiental fue registrada con un Data Logger. Las fecas fueron remojadas en agua por 24 horas y analizadas con ayuda de un microscopio. Se recolectó 148 indicios, entre plumas y fecas principalmente, estimándose una abundancia de 2,18 individuos en los 6,18km recorridos. Se identificó 50 especies de flora silvestre, pertenecientes a 15 familias. Las familias con mayor representatividad fueron Poaceae con 32% y Asteraceae con 22%, mientras que las demás familias representan 37,5%. Las temperaturas más bajas se registraron en los meses de agosto, setiembre y noviembre, con valores que oscilaron hasta los -3,57C°, con una media de 10,57; 11,88 y 13,19C° respectivamente. El agua del hábitat es de buena calidad con un pH 7,6. El suelo que caracteriza la zona ubicada a los 4800 msnm, es de tipo arenoso franco. El 48,6% de la dieta estuvo constituida por semillas y tallos de Juncus sp.

“…Other than the frugivorous cassowary, all other palaeognaths have a varied diet, comprised of leaves, flowers, fruits and grass seeds, as well as dicot herbs and shrubs [74]. Often various insects and small animals are also included in the diets of most palaeognaths, particularly the kiwi, primarily feeding on soil invertebrates [75–77].…”

The phylogenetic significance of the morphology of the syrinx, hyoid and larynx, of the southern cassowary, Casuarius casuarius (Aves, Palaeognathae)

et al. 2019

BackgroundPalaeognathae is a basal clade within Aves and include the large and flightless ratites and the smaller, volant tinamous. Although much research has been conducted on various aspects of palaeognath morphology, ecology, and evolutionary history, there are still areas which require investigation. This study aimed to fill gaps in our knowledge of the Southern Cassowary, Casuarius casuarius, for which information on the skeletal systems of the syrinx, hyoid and larynx is lacking - despite these structures having been recognised as performing key functional roles associated with vocalisation, respiration and feeding. Previous research into the syrinx and hyoid have also indicated these structures to be valuable for determining evolutionary relationships among neognath taxa, and thus suggest they would also be informative for palaeognath phylogenetic analyses, which still exhibits strong conflict between morphological and molecular trees.ResultsThe morphology of the syrinx, hyoid and larynx of C. casuarius is described from CT scans. The syrinx is of the simple tracheo-bronchial syrinx type, lacking specialised elements such as the pessulus; the hyoid is relatively short with longer ceratobranchials compared to epibranchials; and the larynx is comprised of entirely cartilaginous, standard avian anatomical elements including a concave, basin-like cricoid and fused cricoid wings. As in the larynx, both the syrinx and hyoid lack ossification and all three structures were most similar to Dromaius. We documented substantial variation across palaeognaths in the skeletal character states of the syrinx, hyoid, and larynx, using both the literature and novel observations (e.g. of C. casuarius). Notably, new synapomorphies linking Dinornithiformes and Tinamidae are identified, consistent with the molecular evidence for this clade. These shared morphological character traits include the ossification of the cricoid and arytenoid cartilages, and an additional cranial character, the articulation between the maxillary process of the nasal and the maxilla.ConclusionSyrinx, hyoid and larynx characters of palaeognaths display greater concordance with molecular trees than do other morphological traits. These structures might therefore be less prone to homoplasy related to flightlessness and gigantism, compared to typical morphological traits emphasised in previous phylogenetic studies.
