| Abstract | The double-crested cormorant (DCCO) has an extensive range in North America, occurring throughout the interior as well as on both coasts. Mendall (1936) reported that in New England cormorants were eliminated as nesters by the late 19 century. Resident populations in the South-Central United States disappeared, and wintering populations declined through the middle of the 20 century (Jackson and Jackson 1995). In the 1800’s and early 1900’s, numbers of cormorants declined along the Pacific coast (Carter et al. 1995). From 1950 to 1970, the Interior and California populations declined while the Atlantic population merely stopped growing (Hatch 1995). However, by the 1980’s, most populations were increasing (Jackson and Jackson 1995, Carter et al. 1995, Krohn et al. 1995). |
