Bit of a tea leaf, this flier? (4)
I believe the answer is:
teal
'flier?' is the definition.
(teal is a kind of birdanimal)
'bit of a tea leaf' is the wordplay.
'bit of a tea' becomes 'tea' ('tea' is part of 'tea').
'leaf' becomes 'l' (this might be a standard abbreviation which I don't know about).
'tea'+'l'='TEAL'
'this' is the link.
Can you help me to learn more?
(Other definitions for teal that I've seen before include "Duck; greenish-blue colour" , "Small river duck" , "Raise (subject matter)" , "Species of duck" , "Small freshwater duck and colour" .)
