The Lesser Thunderbird (Avesfulmen minori) is the cousin of the common thunderbird (Avesfulmen splendidus). It has a wingspan of up to 3.0 meters, a large hooked beak, talons, and large golden eyes.
Lesser thunderbirds are diurnal carnivores, often hunting fish and small mammals. They nest in mountain peaks and may travel hundreds of kilometers to search for prey. They seem to enjoy electrical storms, and are often seen playing among thunderclouds. There are rumors that these birds can collectively summon thunderstorms. They can project an electrical field that resembles an electromagnetic pulse, which wrecks havoc with electronic components. Thunderbirds have a tendency to explode when they die, presumably from the discharge of their electrically active tissues.
Lesser thunderbirds are found in mountain ranges throughout the Western Hemisphere.
