Habitat Utilization, Seasonal Activity, and Population Size Structure of the Southeastern Crowned Snake Tantilla Coronata

Raymond D. Semlitsch, Kent L. Brown, and Janalee P. Caldwell



Southeastern crowned snakes (Tantilla coronata) were sampled during 1979 from five types of habitat in South Carolina.  Males and females did not differ in snout-vent length (SVL) or body mass, but tail length was sexually dimorphic.  Mature adults ranged in size from 160-250 mm SVL.  Two juveniles were taken in August and September; juveniles represented a disproportionately small part of the snakes collected.  The sex ratio of adults was 2:1 in favor of males.  Tantilla coronata were most active during July and August, and the number of captures was significantly associated with maximum and minimum air temperatures but not with temperature range or rainfall.  Within habitats, xeric locations were more often utilized than mesic locations, but Carolina bays and pine plantations were equally used.
