Kind of heron, for example, by river banks in Egypt (5)
I believe the answer is:
egret
'kind of heron' is the definition.
(I've seen this in another clue)
'example by river banks in egypt' is the wordplay.
'example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'by' says to put letters next to each other.
'river' becomes 'r' (abbreviation for river).
'banks in' suggests removing the centre (the edges or banks of the word).
'egypt' with its middle removed is 'et'.
'eg'+'r'+'et'='EGRET'
'for' is the link.
(Other definitions for egret that I've seen before include "White-feathered wading bird" , "Kind of white heron - greet it" , "flier" , "Greet (anag) -- wading bird" , "Seabird" .)
