Bird nice pal gets to fly (7)
I believe the answer is:
pelican
'bird' is the definition.
(pelican is a kind of bird)
'nice pal gets to fly' is the wordplay.
'gets to fly' is an anagram indicator.
'nice'+'pal'='nicepal'
'nicepal' with letters rearranged gives 'PELICAN'.
(Other definitions for pelican that I've seen before include "Seabird with a large pouched bill" , "In place for large-billed bird" , "Large water bird" , "Aquatic bird - type of road crossing" , "Large-pouched bird" .)
