Visiting sea-eagles east of very small Highland town (9)
I believe the answer is:
inverness
'highland town' is the definition.
(I've seen this before)
'visiting sea-eagles east of very small' is the wordplay.
'visiting' becomes 'in'.
'sea-eagles' becomes 'ernes' (I've seen this before).
'east of' says to put letters next to each other (some letters go to the right of others).
'very' becomes 'v' (abbreviation).
'small' becomes 's' (abbreviation - e.g. clothes size).
'ernes' put after 'v' is 'vernes'.
'in'+'vernes'+'s'='INVERNESS'
(Other definitions for inverness that I've seen before include "Scottish Highlands city" , "overcoat" , "Scottish highland town" , "in Scotland" , "Highland city" .)
