Posted a message like a bird (7)

I believe the answer is:

tweeted

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

'posted' is the definition.

'a message like a bird' is the wordplay.
'a message' becomes 'tweet' (type of online message).
'like a bird' becomes 'ed' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'tweet'+'ed'='TWEETED'

Can you help me to learn more?

(Other definitions for tweeted that I've seen before include "Made a posting" , "used social media?" .)

I've seen this clue in The Mirror.
