The kiwi is a family of nocturnal birds endemic to New Zealand.. While it is difficult to say which came first, nocturnality or diurnality, a hypothesis in evolutionary biology, the nocturnal bottleneck theory, postulates that in the Mesozoic, many ancestors of modern-day mammals evolved nocturnal characteristics in order to avoid contact with the numerous diurnal predators.

In some species, female owls stay at their nest with their eggs while it is the responsibility of the male to bring back food to the nest. [13] If food is scarce, the male first feeds himself before feeding the female. [14] Small birds, which are agile, are an important source of food for owls.
Up until the early 19th century, the common nighthawk and the whip-poor-will were thought to be one species. The latter's call was explained as the nocturnal expression of the common nighthawk. Alexander Wilson, "The Father of American Ornithology", correctly made the differentiation between the two species.
This led to a surge in scientific interest in the species, which resulted in many birds being trapped for museums and zoos. The species was also trapped for food and was considered a delicacy by European colonisers. It was also fashionable to own kagus as pets. A campaign was run from 1977–1982 to phase out the pet trade in kagus.
