Male bird finally spotted on garden tool (5)
I believe the answer is:
drake
'male bird' is the definition.
(I've seen this before)
'finally spotted on garden tool' is the wordplay.
'finally' suggests the final letters.
'on' says to put letters next to each other.
'garden tool' becomes 'rake' (tool used when gardening).
The last letter of 'spotted' is 'd'.
'd'+'rake'='DRAKE'
(Other definitions for drake that I've seen before include "Hoe user" , "Seaman" , "sea captain" , "Raked (anag.)" , "Male bird" .)
