Also the name of a beautiful book of poetry by Jake Adam York, a group of starlings is known as a “murmuration.” One could make the case that the birds are America’s most literary. Each of the hundreds of millions of European starlings currently inhabiting North America is a descendant of the approximately 100 birds released in New York City’s Central Park in the early 1890s. They were released by a society intent on populating America with each of the birds mentioned in Shakespeare’s plays.
