Glass pigeon (7)

Ross

I believe the answer is:

tumbler

I believe this is a double definition.

'glass' is the first definition.
(tumbler is a kind of glass)

'pigeon' is the second definition.
(tumbler is a kind of pigeon)

(Other definitions for tumbler that I've seen before include "One repeatedly turning over" , "Gymnast with a glass" , "appears to be falling" , "A glass; part of lock" , "Constantly dropping" .)

I've seen this clue in The Telegraph.
