The Names 'Goatsucker' and 'Nightjar'



Several people have recently commented to me on the unusual bird family names 'Goatsucker' and 'Nightjar'.  The families include our three Utah representatives, the Common Nighthawk, the Lesser Nighthawk, and the Common Poorwill, and birds such as the Chuck-will's-widow and Whip-poor-will that inhabit other parts of the U.S.  I'll let Diana Wells explain the family names' bird-word etymology.  Ms Wells authored 100 Birds and How They Got Their Names
 
"Goatsuckers often stay near livestock, where the insects they eat congregate.  It was once thought that at night they also sucked the milk of goats, whereupon, wrote Aristotle, 'the udder withers and the goat goes blind.'  Their family name, Caprimulgidae, comes from the Latin caper, 'goat,' and mulgere, 'to milk.'  Their Italian and German names, succiacapre and Ziegenmelker, have the same meaning.  They are called nightjars, too, for their 'jarring' nocturnal cries."
 
When I acquired this book, 'Goatsucker' was the first name I looked up because it sounds so udderly ridiculous. 
 
Wonderful little book, 100 Birds... is, and an excellent reference so that you can be the delight of the next family reunion or block party.
