Jackdaws

Walters (301), who is an ornithologist as well as a Savoyard, explains that jackdaw is “the English name for Corvus monedula, a small species of crow. The allusion is to Aesop’s fable of the jackdaw who dressed himself in peacock feathers to appear better than he really was, and was rejected both by his own kind and those whom he sought to emulate.”
