Sea-Bird started in three races as a two-year-old, winning his first two, the Prix de Blaison at Chantilly by a short head (started slowly) and the Critérium de Maisons-Laffitte by two lengths from Blabla (who won the Prix de Diane the following year).
As a three-year-old, Sea-Bird won all five starts, starting with a three-length win in the Prix Greffulhe.
