Snails preyed upon by the Grenada Hook-billed Kite (Chondrohierax uncinatus mirus) were collected... more Snails preyed upon by the Grenada Hook-billed Kite (Chondrohierax uncinatus mirus) were collected from two nesting sites in different regions and habitats on Grenada, with the aim of better understanding the diet of this endemic and endangered subspecies. Apart from the large snail Megalobulimus oblongus, which was present in the environment but not consumed by the kites, all five species previously reported in the literature (Bulimulus wiebesi, Plekocheilus glaber, Drymaeus binominis, Orthalicus zebra, and Pleurodonte perplexa) were documented as prey. Land snail species occur in variable numbers according to habitat type and localized environmental conditions, illustrating the kite's ability to exploit distinct areas of the island. Land snails consumed by the kite included both arboreal and ground-dwelling species, representing all the medium-sized (20-40 mm) species occurring on Grenada. Variation in snail species proportions were evident when comparing assemblages collected beneath nests to those scattered in the immediate vicinity of nests, suggesting seasonal factors or species selection for feeding young may influence the kite's food habits.

Its stratigraphy covers the latest Pleistocene and the second half of the Holocene. An archaeological level of the Late Ceramic Age was evidenced, as well as older levels, rich in bones and invertebrate remains, for which the question of a human contribution to the assemblage formation was raised.New excavations were carried out in 2018 and 2019 with three perspectives: 1) increase the vertebrate assemblage to describe the succession of Holocene vertebrate biocenoses on the island, 2) refine the deposit chronology and the stratigraphic resolution of the collected assemblages, and 3) collect evidence useful for discussing a human use of the site during the Preceramic period.These excavations revealed the funerary function of the site during the late phase of the Late Ceramic Age with the discovery of an Amerindian burial in the highest part of the deposit. They also demonstrate the Precerami...

Celle-ci se situe en contrebas du plateau du Fort, à quelques dizaines de mètres de l’ancien fort. Des opérations précédentes dans le quartier ont déjà révélé la présence de vestiges du xixe s. et d’indices mal caractérisés d’occupations du xviiie s. et de la période précolombienne. De fait, ce secteur du plateau du Fort, en rive nord de l’embouchure de la Roxelane, constitue, dès 1635, l’embryon du bourg..
