Description

<p>White-bellied heron Ardea insignis (WBH) is critically endangered not many aspects of its basic ecology nor are threats to the species clearly understood. The goal of this study was to analyze WBH foraging microhabitat selection, foraging behavior and prey preferences in two river basins in Bhutan likely home to one of the largest remaining populations of WBH. The riffle and pool were most commonly used microhabitats with 80 and 62 feeding observations. WBH exploited three genera of fish species (Gara, Salmo, and Schizothorax) of which Schizothorax (64 %) was the most dominant genus. This study fills the existing knowledge gap and provides evidence to support effective policy and management implementation for further protection of its riverine habitat and enhancement of food resource for long time survival of WBH.</p>
