Zusammenfassung:99 Recoveries of Black-crowned Night-Herons were analyzed (Nycticorax nycticorax ) banded in Canada during 1942-1986 (97 banded as chicks, one banded as an after-hatching year bird, one banded at an unknown age). For Black-crowned Night-Herons banded in Canada, the majority of adults and yearlings were recovered within 250 km of their original banding locations during April through August, a few even within the same 10' latitude x 10' longitude block. This suggests strong tenacity to natal area and possibly to the natal colony sites.
