Name of various vehicles used by the Campbell family to set land and water speed records (8)

I believe the answer is:

bluebird

(Other definitions for bluebird that I've seen before include "American singer" , "Donald Campbell's speedboat - relative of thrush" , "American avian" , "North American songbird (once seen over Dover?)" , "American member of thrush family (seen over Dover?)" .)

I've seen this clue in The Independent.
