Definition: The term "crested swift" refers to a type of bird that is found in Southeast Asia and the East Indies. These birds are similar to true swifts but have a noticeable feature: they have upright crests on their heads. Additionally, unlike some other swifts that nest in cliffs or buildings, crested swifts prefer to nest in trees.
In more advanced contexts, you might encounter discussions about the crested swift in scientific texts or ornithology (the study of birds). You could say: - "Ornithologists conducted a study to observe the mating habits of the crested swift in its natural habitat."
Currently, there are no widely recognized idioms or phrasal verbs that specifically include "crested swift." However, you can use the word "swift" in common expressions like: - "Make a swift exit" meaning to leave quickly.
