WALTERS J (1981) Breeding Places as a criterion for probably breeding. LIMOSA 54 (2): 65-66.

A bird possessing fully developed brood patches may have in€upted incubation recently and left the breeding area over large distances, in many cases far beyond the borders of its breeding square. Therefore, the relative EOAC code C8 - also applied in the Dutch atlas of breeding birds - has little or no value for the indication of "probable breeding" in a certain square. Though true for probably all species, a most convincing example was that of a newly dead Kittiwake Rissa tridactyla found near Amsterdam on 3 July 1980. This bird still had three fully developed brood patches though quite certainly it was not breeding in the area. The C8 code may have been used infrequently in compiling the Dutch atlas. It is regretted that pertinent evidence, as given in the Danish atlas (Dybbro 1976), is lacking.
