A total of 27 colonies in six provinces were identified during the field- 
work of which eight were not mentioned by Kasparek (1989). 
Furthermore accurate counting of other colonies meant that a clearer 
idea of the number of nests contained therein was reached. Observ^ers 
are urged to make counts of Rook colonies that they find, and in par- 
ticular search for new colonies in regions of Turkey where no nesting 
sites have yet been identified.
