Family histories displayed by these predators? (6)
I believe the answer is:
eagles
'these predators?' is the definition.
(eagle is a kind of predator)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for eagles that I've seen before include "Birds with a sea leg?" , "Large birds of prey" , "Noble birds that live in eyries" , "Great birds in eyries" , "rock group?" .)
