“…The studied species were the ringed kingfisher (Megaceryle torquata) and the Amazon kingfisher (Chloroceryle amazona), which occur throughout Brazil in coastal areas, wetlands, rivers, dams, lakes, and lagoons. They are considered piscivores, but occasionally can consume small crustaceans (Frisch, 1981;Spiller, 2018;Baretta et al, 2006;Naiff et al, 2011). The two studied species share the same niche, however there are differences between foraging habits, such as diving height, depth for capturing prey and foraging locations; as exemple, the Amazon kingfisher prefers shallow and shady margins, whereas the ringed kingfisher uses deeper areas and places with rocks with little overlap.…”
