Yes coot can be exchanged for prairie wolves (7)
I believe the answer is:
coyotes
'prairie wolves' is the definition.
(I've seen this in another clue)
'yes coot can be exchanged' is the wordplay.
'can be exchanged' indicates anagramming the letters.
'yes'+'coot'='yescoot'
'yescoot' anagrammed gives 'COYOTES'.
'for' is the link.
(Other definitions for coyotes that I've seen before include "Prairie wolves" , "North American predators" , "American prairie dogs" .)
