What's the difference between nightjar and oilbird?
Nightjar
Definition:
(n.) A goatsucker, esp. the European species. See Illust. of Goatsucker.
Example Sentences:
(1) As the sky turned lilac, I saw hundreds flutter past – red and blue macaws in pairs, companies of green parrots, flotillas of ibis gliding in elegant V-formation, as well as toucans, nightjars, lapwings and pauraques.
(2) This tropical relative of the nightjars is another bird so bizarre you couldn’t make it up: a creature of the night with huge eyes, bristles around its bill to help it detect flying insects in the darkness, and a fine line in camouflage; only when Doug uses his laser pointer to show me where it is, can I even manage to see it.
(3) Look and listen out for Pipistrelle bats leaving their roosts to hunt for small insects; nightjars chasing moths; the occasional cow, employed to keep down the scrub.
