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 before)
'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).
'banks in' means to remove the middle letters (the edges or banks of the word).
'egypt' with its middle taken out 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" .)
