Radiotelemetric Study of Activity and Movements of Racers
(Coluber constrictor) Associated with a Carolina Bay in
Racers (Coluber constrictor) were monitored with radiotelemetry in an old
field/forest habitat surrounding a Carolina bay in South Carolina. Racers were
active on approximately 70% of days; inactive snakes usually were in ecdysis.
Active racers were relocated on the ground surface (40%), above ground in
shrubs and trees (35%), and underground (25%). Habitats in which racers were
relocated were thickets and grassland shrubs (50%), woodland/forest (25%),
and grassland (25%). Active snakes moved an average of 104 m/d within home
ranges averaging 12.2 ha estimated as minimum convex polygons. The home
range of each snake included at least a portion of the bay and overlapped with
home ranges of other snakes. In comparison with other studies of racers in which
data were collected, analyzed, and presented in the same manner as in this study,
home range size and daily movement of South Carolina racers were significantly
greater. Possible explanations for the greater movement include trophic level
differences and a proximate response to a local drought.
