State bird of Arizona or South Carolina
I believe the answer is:
wren
'state bird of arizona or south carolina' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for wren that I've seen before include "18 [SWAN] 's little cousin" , "Small singer" , "English church architect, d. 1723" , "one leaving evidence all around London monument" , "Member of the former Women's Royal Naval Service" .)
