Pleased inside to have bird from the Orient (7)
I believe the answer is:
eastern
'from the orient' is the definition.
(I've seen this before)
'pleased inside to have bird' is the wordplay.
'inside' says to take the centre.
'to have' says to put letters next to each other.
'bird' becomes 'tern' (tern is a kind of bird**).
The centre of 'pleased' is 'eas'.
'eas'+'tern'='EASTERN'
(Other definitions for eastern that I've seen before include "See 11" , "Coming from the Orient" , "Earnest (anag.)" , "Nearest (anag) - oriental" , "towards daybreak?" .)
