Nightwing

A nightwing is a species of kingfisher part of a kookaburra family native throughout Australia, but has since been introduced to Europe and North America, where they are, by all acounts, thriving and are invasive. Unlike just about any other member of the kingfisher family, as their name suggests, nightwings are almost entirely nocturnal, probably to reduce competition from other kingfishers. They have the niche like that of a laughing kookaburra, feeding on the same type of foods, and the niche of fish-eating kingfishers, being able to catch fish from above water with their beaks. They resemble an almost-completely black-colored laughing kookaburra, but are slightly leaner in build. Their calls consists of sounds such as their famous "laughing", which resembles a cross between a laughing kookaburra's "laugh" and a jungle crow's cawwing, giving them very deep-pitched laughter-like sounds. They are not endangered in their native range in Australia as they tolerate human activities and adapt well to city life and suburban life, even in their nonnative (invasive) range, it is no exception as they tolerate the cold and heat, as well as arid and humid areas.
