Second bird, one from America originally (6)
I believe the answer is:
mohawk
'one from america originally' is the definition.
I can't tell whether this definition defines the answer.
'second bird' is the wordplay.
'second' becomes 'mo' (both are short periods of time).
'bird' becomes 'hawk' (hawk is a kind of bird**).
'mo'+'hawk'='MOHAWK'
Can you help me to learn more?
(Other definitions for mohawk that I've seen before include "American native; skating step" , "American runner" , "(N Amer.) Indian" , "Brave" , "Member of a native American people and a haircut" .)
