Seabird with storm and Leach's varieties in the UK (6)

I believe the answer is:

petrel

(Other definitions for petrel that I've seen before include "18's [BIRD]" , "Seabird sounds like fuel" , "Bird that sounds like fuel" , "Mother Carey's chicken" , "Seabird (that may be stormy)" .)

I've seen this clue in The Times.
