Abstract
We report two previously undescribed foraging techniques used by Snowy Egrets (Egretta thula) and Yellow-crowned Night-Herons (Nyctanassa violacea) to catch crawfish (Procambarus spp.). Snowy Egrets were selecting crawfish that had recently molted their shells and Yellow-crowned Sight-Herons were targeting crawfish that were emerging from their burrows. These observations were conducted on commercial crawfish ponds near Catahoula, LA, USA.
