Hound killing black bird (5)
I believe the answer is:
eagle
'bird' is the definition.
(eagle is a kind of bird)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for eagle that I've seen before include "High-flyer" , "A birdie (or better!)" , "Fine achievement on course" , "Erne, perhaps" , "Valuable piece" .)
