Nesting Success and Mortality of Nestlings in a Coastal Alabama Heron - Egret Colony, 1976


A heronry at Cat Island, Alabama was surveyed throughout the 1976 breeding season to determine colony structure and survivability of young Ardeidae during varying weather conditions. A total of 155 nests were tagged and the clutch of each monitored until the nestlings abandoned the nests. Offspring of herons nesting during unfavorable weather conditions of late Spring suffered significantly higher mortality than birds nesting in mid-summer. Species nesting on Cat Island include the Louisiana Heron, Snowy Egret, Great Egret, Cattle Egret, Little Blue Heron, Green Heron, and Glossy Ibis.
