This is a display only a female grackle would like! This contorted ball of feathers is a Carib Grackle male in full "ruff-out" display. While he cocks his keel-shaped tail he raises his wings, points the bill up, rolls his eyes back and sings...if you call that a song. But what has caught my attention is that the males sing different songs on different island, sometimes radically different songs.
