The Band-rumped Storm Petrel, Madeiran Storm Petrel, or Harcourt's Storm Petrel (Oceanodroma castro) is of the storm petrel family Hydrobatidae.
The Band-rumped Storm Petrel is 19–21 cm in length with a 43–46 cm wingspan, and weighs 44–49 g. It is mainly black with an extensive white rump. Similar to Leach's Storm Petrel with the forked tail, long wings, and flight behaviour, but Leach's has a more forked tail and differently shaped white rump.
