Mine includes rising little Scottish shore bird (6)
I believe the answer is:
peewit
'shore bird' is the definition.
(peewit is a kind of shore bird)
'mine includes rising little scottish' is the wordplay.
'mine' becomes 'pit' (down the pit).
'includes' means one lot of letters goes inside another.
'rising' is a reversal indicator (going up in a down clue).
'little scottish' becomes 'wee'.
'wee' backwards is 'eew'.
'pit' enclosing 'eew' is 'PEEWIT'.
(Other definitions for peewit that I've seen before include "Lapwing turned up in a wee pit" , "Flighty type" , "Lapwing - ie wept (anag)" , "Northern lapwing" , "Kind of plover; let it weep" .)
