Patterns of Corn Snakes, Elaphe gultata, of Different Phenotypes
of the House Mouse, Mus musculus
C. Smith and David Watson
Factors affecting prey selection of the corn snake, Elaphe
guttata, were determined using different phenotypes of Mus musculus
presented on different colored substrates.
A significant difference was noted in the selection of light brown over
agouti mice when tested on light brown soil.
Comparisons of matching versus contrasting mice on all substrates were
not significant. No significant
difference was noted in the selection of small versus large mice of the same
color. Laboratory-raised mice were
chosen with greater frequency than wild mice of the same color.
Recognition of prey leading to capture occurred in 73% of the trials
within 30 cm, 17% to 60 cm, and 7% to 90 cm, and 3 % greater than 90 cm.
Unlike results reported for avian predators, movement and proximity of
prey appeared to be more important than color conspicuousness in selection
patterns of this terrestrial predator.
