An owl in a port (5)
I believe the answer is:
tawny
'port' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for tawny that I've seen before include "Orange-brown in colour" , "port" , "Brownish-yellow" , "Golden brown" , "Yellowish-brown - kind of owl" .)
