It's no surprise that the Alessi Kettle with Bird Whistle has sold more units than any other item in Alessi history. Designed by Michael Graves in 1985, the Alessi bird kettle has a youthful personality and a simple geometry, allowing it to heat faster than other kettles thanks to its tapered stainless steel body and spout. The bird spout cheerfully whistles when the water has reached a boil.
