Check for second time in social media platform for one watching birds (8)
I believe the answer is:
twitcher
'one watching birds' is the definition.
(term for a birdwatcher)
'check for second time in social media platform' is the wordplay.
I cannot quite see how this works, but
'check' could be 'ch' (I've seen this in other clues) and 'ch' is present in the answer.
'time' could be 't' (abbreviation) and 't' is found within the answer.
This may be the basis of clue (or it may be nonsense).
'for' is the link.
(Other definitions for twitcher that I've seen before include "Rare bird spotter" , "pursuing hobby?" , "Nervous person" , "Spasmodic" , "One not still" .)
