Eastern flycatcher (6)
I believe the answer is:
phoebe
'eastern flycatcher' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for phoebe that I've seen before include "Greek goddess, daughter of Uranus" , "Old poetic name for moon, and satellite of Saturn" , "Apollo's sister Artemis, the moon goddess" , ""moony" woman" , "girl" .)
