摘要

摘要 根据相机捕获的图像,我们记录了渔猫Prionailurus viverrinus对殖民地水鸟巢的主动觅食尝试。巢建在孟加拉国东北部豪尔盆地地区一棵8米高的印度橡树Barringtonia acutangula的树冠上。2022 年,记录了两起渔猫触及雏鸟巢穴的事件。在一次事件中,猫杀死了四只雏鸟。该物种主要以鱼类为食,在进化过程中适应了半水生的狩猎环境。这些记录首次提供了渔猫树栖狩猎行为的已知证据。

A treetop diner: camera trapping reveals novel arboreal foraging by fishing cats on colonial nesting birds in Bangladesh
Abstract Based on camera trap images, we document active foraging attempts on nests of colonial waterbirds by a fishing cat Prionailurus viverrinus. The nests were built in the canopy of an 8-m-tall Indian Oak tree Barringtonia acutangula in the Haor Basin region, northeast Bangladesh. In 2022, two events of fishing cats reaching nests with fledglings were documented. In one event, the cat killed four fledglings. The species primarily follows a piscivorous diet and is evolutionarily adapted for semi-aquatic hunting niches. These records provide the first known evidence of the arboreal hunting behaviour observed in the fishing cat.

期刊介绍: Mammalia is an international, multidisciplinary, bimonthly journal devoted to the inventory, analysis and interpretation of mammalian diversity. It publishes original results on all aspects of the systematics and biology of mammals with a strong focus on ecology, including biodiversity analyses, distribution habitats, diet, predator-prey relationships, competition, community analyses and conservation of mammals. The journal also accepts submissions on sub-fossil or recently extinct mammals.
