Data from: Strategic predatory pursuit of the stealthy, highly maneuverable, slow flying bat Corynorhinus townsendii
<p class="MsoNormal">A predator's capacity to catch prey depends on its ability to navigate its environment in response to prey movements or escape behavior. In predator-prey interactions that involve an active chase, pursuit behavior can be studied as the collection of rules that dictate how a predator should steer to capture prey. It remains unclear how variable this behavior is within and across species since most studies have detailed the pursuit behavior of high-speed, open-area foragers. In this study, we analyze the pursuit behavior in 44 successful captures by <em>Corynorhinus townsendii</em>, Townsend's big-eared bat (<em>n</em> = 4). This species forages close to vegetation using slow and highly maneuverable flight, which contrasts with the locomotor capabilities and feeding ecologies of other taxa studied to date. Our results indicate that this species relies on an initial stealthy approach, which is generally sufficient to capture prey (32 out of 44 trials). In cases where the initial approach is not sufficient to perform a capture attempt (12 out of 44 trials), <em>C. townsendii</em> continues its pursuit by reacting to prey movements in a manner best modeled with a combination of pure pursuit, or following prey directly, and proportional navigation, or moving to an interception point.</p>

Data from: Prey size and dietary niche of Rafinesque's big-eared bat (Corynorhinus rafinesquii)
Bats in the genus Corynorhinus possess a suite of morphological characters that permit them to effectively use both gleaning and aerial-hawking foraging strategies to capture Lepidoptera. Consequently, they occupy a specialized feeding niche within North American bat assemblages and are of particular interest for dietary studies. We collected fecal pellets from a colony of C. rafinesquii (Rafinesque's Big-Eared Bat) at Mammoth Cave National Park during August–October 2011 and amplified cytochrome-c oxidase subunit 1 fragments of prey from these pellets. We used the Barcode of Life Database to identify prey, and evaluated the size of prey species based on published values. The mean wingspan of prey we recorded from our samples was smaller than average values reported for Rafinesque's Big-Eared Bat using traditional methods (P ≤ 0.01), suggesting that surveys of culled insect parts beneath roosting sites may lead to biased estimates of the size and breadth of prey species eaten by gleaning bats. Mean wingspan of lepidopteran prey consumed by Rafinesque's Big-Eared Bat in our study was larger (P ≤ 0.01) than values reported for the Myotis septentrionalis (Northern Long-Eared Bat ), which is a smaller, sympatric gleaner in eastern North America. Further, comparisons of our diet data with abundance of prey suggest macrolepidopteran taxa are consistently consumed by Rafinesque's Big-Eared Bat to greater degree than microlepidotera. Our findings suggest that North American Corynorhinus consume a wider range of sizes and species of Lepidoptera than previously reported in studies based solely on identification of culled prey-wings beneath feeding roosts.
