Use "cuckoos" in a sentence
"I am deliberately avoiding bringing in cuckoos and accipitrids (the latter noted by Olson as being possible allies of the turacos) in order to keep things simple-ish."
"Mr. Swainson has well remarked,28 that with the exception of the Molothrus pecoris, to which must be added the M. niger, the cuckoos are the only birds which can be called truly parasitical; namely, such as "fasten themselves, as it were, on another living animal, whose animal heat brings their young into life, whose food they live upon, and whose death would cause theirs during the period of infancy.""
"Scarcely less vociferous than the cuckoos are the owls."
