Shady Canadian types of drones flying over Pelly Peak (6)
I believe the answer is:
maples
'shady canadian types' is the definition.
Although both the answer and definition are plural nouns, I don't understand how they can define each other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for maples that I've seen before include "(Canadian) trees" , "Acers" , "MP sale of trees" , "Trees of Canada" , "Trees providing syrup" .)
