Además documento la depredación del caracol gigante africano (Achatina fulica). Refiero la manipulación del caracol, su extracción de la concha y deglución mientras el individuo posaba en una rama de árbol (Triplaris cumingiana), rodeado de cultivos de cacao (Theobroma cacao). Además, alrededor del sitio de avistamiento registré cinco conchas de caracol gigante africano con perforaciones atribuibles al gavilán pico gancho. Este registro confirma su presencia dentro de la provincia y adiciona un caso de eumelanismo en Ecuador. Sugiero al gavilán pico gancho como un controlador biológico del caracol africano.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract This note describes the uncommon presence of an individual melanic (dark morph) Hook-billed Kite (Chondrohierax uncinatus uncinatus) in southern Ecuador. In addition the depredation of the giant African snail (Achatina fulica) is documented. The manipulation of the snail, its extraction of the shell, and swallowing while the individual posed in a branch of tree (Triplaris Cumingiana), surrounded by cacao crops (Theobroma cacao) is detailed. Five shells of giant African snail with perforations attributable to the Hook-billed Kite were discovered. This registry confirms the presence of the dark morph within the province in Ecuador. It is suggested to the Hook-billed Kite as a biological controller of the African snail.]]></p></abstract>
