Flying Fishermen II

The common kingfisher (Alcedo atthis), for example, has a documented fishing success rate of around 74% in favorable conditions, according to behavioral studies.

This high efficiency comes from a combination of monocular depth estimation, a steep dive angle (~45–60°) to minimize water refraction distortion, and rapid head stabilization just before impact.

Their eyes switch to underwater vision using their flattened cornea and a translucent nictitating membrane, allowing them to track fish with surprising precision during the split-second dive.
