Bird gets friend up with flying apparatus (7)
I believe the answer is:
lapwing
'bird' is the definition.
(lapwing is a kind of bird)
'friend up with flying apparatus' is the wordplay.
'friend' becomes 'pal' (pal can mean a friend).
'up' is a reversal indicator (in down clue: letters go upwards).
'with flying apparatus' becomes 'wing' (I can't explain this - if you can you should believe this answer much more).
'pal' in reverse letter order is 'lap'.
'lap'+'wing'='LAPWING'
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for lapwing that I've seen before include "Plover, pewit" , "wader" , "Green plover" , "Type of plover" , "Variety of plover" .)
