Flier associable with Chekhov (7)
I believe the answer is:
seagull
'flier' is the definition.
(seagull is a kind of birdanimal)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for seagull that I've seen before include "Bird paradoxically fond of landfill sites" , "Avian scavenger" , "Main creature" , "One sitting atop mast perhaps" , "Marine bird" .)
