P. C. Frederick T. W. Custer 1990 The authors' objective was to describe egg size in relation to laying order for Great Egrets (Casmerodius albus ), Snowy Egrets (Egretta thula ), and Black-crowned Night-Herons (Nycticorax nycticorax ) in a southern Texas colony and Great Egrets in a southern Florida colony. Based on egg-size patterns in other colonial waterbirds and the occurrence of brood reduction in egrets and herons, they predicted that the final egg laid in a clutch would be smaller than those laid earlier. application/pdf 10.2307/1368698 en Oxford Academic Egg size and laying order of snowy egrets, great egrets, and black-crowned night-herons article
