Résumé :	Measurements of live-captured adult and hatch-year Reddish Egrets (Egretta rufescens) from Texas (n = 29 and 25, respectively) and Florida (n = 7 and 3, respectively) are reported. Mass, tarsus length, and culmen length were used to compare sexes and ages of Reddish Egrets. Adult males (n = 17) were significantly larger than adult females (n = 19) in all parameters, and hatch-year Reddish Egrets were significantly smaller than adults in all parameters. Additionally, considerably larger measurements were recorded on average than those previously available for Reddish Egrets. These measurements provide updated information on the morphometry of Reddish Egrets that will be useful in understanding life history strategies and for planning future studies.
