 There has also been a musical interpretation among the ten on David P. Shortland's Australian recording, "Aesop Go HipHop" (2012), where the sung chorus after the hip hop narration underlines what can be achieved by incremental effort, "Little by little, bit by bit".The Roman naturalist Pliny the Elder is the earliest to attest that the story reflects the behaviour of real-life corvids.In August 2009, a study published in "Current Biology" revealed that rooks, a relative of crows, do just the same as the crow in the fable when presented with a similar situation.
