All animals have defenses against predators, but assessing the effectiveness of such traits is challenging. Neotropical katydids (Orthoptera: Tettigoniidae) are an abundant, ubiquitous, and diverse group of large insects eaten by a variety of predators, including substrate-gleaning bats. Gleaning bats capture food from surfaces and usually use prey-generated sounds to detect and locate prey. A ...

Inspired by the film documentary The Gleaners and I, the paper defines two senses of gleaning: (1) generally, the collection of items in small quantities, and (2) more specifically, the collection of items missed or rejected during previous harvesting. As an activity, gleaning in both senses is a neglected but essential activity in the solving of problems of lack of resource, especially now in ...

We present behavioural data demonstrating that the little brown bat, Myotis lucifugus, and the northern long-eared bat, M. septentrionalis, can glean prey from surfaces and take prey on the wing. Our data were collected in a large outdoor flight room mimicking a cluttered environment. We compared and analysed flight behaviours and echolocation calls used by each species of bat when aerial hawki...

Echolocating bats have historically been classified as either loud aerial hawkers or whispering gleaners. Some bat species can forage in multiple ways and others have demonstrated limited flexibility in the amplitude of their echolocation calls. The desert long-eared bat, Otonycteris hemprichii, has been said to be a passive gleaning whispering bat preying on terrestrial arthropods such as scor...

Many coastal communities depend on ecosystems for goods and services that contribute to human well-being. As long-standing interactions between people nature are modified by global environmental change, dynamic diversified livelihood strategies enable seasonal adaptation will be critical vulnerable communities. However, the success of such depends a range poorly understood influences. Gleaning,...
