European Starling

European Starling

The common starling was first described by Carl Linnaeus in his Systema Naturae in 1758 under its current binomial name. Sturnus and vulgaris are derived from the Latin for “starling” and “common” respectively. The Old English staer, later stare, and the Latin sturnus are both derived from an unknown Indo-European root dating back to the second millennium BC. “Starling” was first recorded in the 11th century, when it referred to the juvenile of the species, but by the 16th century it had already largely supplanted “stare” to refer to birds of all ages. The older name is referenced in William Butler Yeats’ poem “The Stare’s Nest by My Window”. The International Ornithological Congress’ preferred English vernacular name is common starling.

Common Grackle

Common Grackle

Common Grackle

Grackles have a unique adaptation in the keel within their bill which allows them to crack and cut hard nuts or kernels. The keel projects downward from the horny palate and is sharper and more abrupt anterior. It extends below the level of the tomium and is used in a sawing motion to score open acorns or dried kernels. Large adductor muscle within their jaw compared to other icteridae also makes this adaptation even more useful for opening hard seeds and acorns.
Along with some other species of grackles, the common grackle is known to practice “anting”, rubbing insects on its feathers possibly to apply liquids such as formic acid secreted by the insects.
