Post online and call from branch? (5)

Ross

I believe the answer is:

tweet

I'm a little stuck... Click here to teach me more about this clue!

This clue could be a double definition.

'post online' is the first definition.

'call from branch?' is the second definition.
'tweet' can be an answer for 'call' (I've seen this before). I am unsure of the 'from branch?' bit.

'and' is the link.

Can you help me to learn more?

(Other definitions for tweet that I've seen before include "Message from Trump?" , "little message" , "Chirp of a small bird" , "Bird noise" , "Note from flier" .)

I've seen this clue in The Sun.
