Wild glee when trapping a bird of prey (5)

I believe the answer is:

eagle

I'm a little stuck... Click here to teach me more about this clue!

'bird of prey' is the definition.
(eagle is a kind of bird of prey)

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for eagle that I've seen before include "might one be bald?" , "high-flier" , "Bird of prey, may be golden" , "Large bird of prey" , "Aglee (anag.)" .)
