The common koels are three species of cuckoos. They have commonly been considered conspecific under the scientific name Eudynamys scolopaceus, but are increasingly treated as separate species:
- Asian Koel, Eudynamys scolopaceus.
- Black-billed Koel, Eudynamys melanorhynchus.
- Pacific Koel, Eudynamys orientalis.
- Australian Koel, Eudynamys (orientalis) cyanocephalus.
Famous quotes containing the word common:
“It is quite a common and vulgar thing among humans to understand, foresee, know and predict the troubles of others. But oh what a rare thing it is to predict, know, foresee and understand one’s own troubles.”
—François Rabelais (1494–1553)
