The use of a netgun combined with other techniques facilitated the live capture of the Western Grebe Aechmophorus occidentalis occupying a shallow water harbor, with boat traffic, and abundant underwater structure. Transportability and adaptability rendered the netgun an effective tool, in this constrained environment. Haul-out structures such as nests were absent and grebes remained either swimming or floating, throughout their duration. Therefore, in-water access was imperative. Upon capture, grebes were then kept in captivity, to conduct in-laboratory investigations. An undertaking such as this has not been reported before. No grebes were injured during this procedure and capture rate was considered good.
