Males making money in America (5)
I believe the answer is:
bucks
This might be a double definition.
'males' is the first definition.
The answer and definition can be both animals as well as being plural nouns.
Maybe there's an association between them I don't understand?
'money in america' is the second definition.
'bucks' can be an answer for 'money' (informal term for dollars). I am not sure about the 'in america' bit.
'making' acts as a link.
Can you help me to learn more?
(Other definitions for bucks that I've seen before include "County to northwest of London (abbrev.)" , "Male rabbits" , "Goes against" , "Foreign cash" , "overseas money" .)
