From an article called “top dogs” in good place magazine

Starlings, like Handwerker and myself, are European immigrants to America. They arrived in 1890, when a wealthy Bronx landowner and Shakespeare fantastic named Eugene Schieffelin released 60 of them into Central Park as part of his mission to introduce every bird mentioned in the Bard’s plays to the States. None of the other birds Schieffelin brought to America survived, but the starlings thrived in their new home. Today, there are over 200 million of them in North America

So many questions come to mind reading this. How many birds are mentioned in Shakespeare’s plays? How many of each species did Schieffelin get hold of and release? Did he release them all in Central Park? At one time, or over a number of days/weeks/years? Wikipedia to the rescue!
