Birdsong way up entertains pair on front of Weirdos From Another Planet (6)
I believe the answer is:
tweets
'up entertains pair on front of weirdos from another planet' is the definition.
I can't tell whether this definition defines the answer.
'birdsong way' is the wordplay.
'birdsong' becomes 'tweet' (I've seen this before).
'way' becomes 's' (Compass direction - South).
'tweet'+'s'='TWEETS'
Can you help me to learn more?
(Other definitions for tweets that I've seen before include "Chirps social media postings" , "Sends social media comments, information, etc" , "Social media messages" , "online comments" , "Short internet messages" .)
