Eumeces fasciatus
In the course of the study approximately 30 individuals were released or
accidentally escaped at places other than the locations where they were
originally taken. Some of these were young hatched in the laboratory,
some were of unknown origin, their locality tags having been lost before
release while they were being handled in the laboratory, or escaped from
defective cloth bags while they were awaiting processing or release, and
some taken on remote parts of the Reservation or nearby land were
deliberately released on one of the study areas with the idea that they
would replace skinks of the same sex and age, recently eliminated
through an accident of trapping or handling. Ten were released in Skink
Woods, ten at the pond rock pile, eight at the laboratory building, and
two near Rat Ledge. In no instance was a transferred skink known to have
found its way back to an original home range, although some might have
done so with fairly short trips of only a few hundred feet, and the
chances of recapturing them would have been good. Therefore it seems
that homing instinct is either wholly lacking or but feebly developed.
The incidence of recaptures was low, only four for the entire group,
suggesting a tendency to wander away from the area of release before
settling down on a home range. One young found on May 11, 1950, in the
laboratory where it probably had escaped, was released in Skink Woods,
and was recaptured three times in the summer of 1951, in what seemed to
be a home range within 80 feet of the point of release. Another young
of unknown origin released in Skink Woods on May 18, 1950, was
recaptured six days later 160 feet away. Five hatchlings from a clutch
of eggs incubated and hatched in the laboratory, were released in Skink
Woods on August 8, 1952. The following April two of them were
recaptured, only 20 feet and 25 feet respectively, from the point of
release. The movements and dispersal of this group from the point of
release probably paralleled that of a typical brood dispersing from its
nest after hatching under natural conditions. An adult male captured
just off the Reservation was released at the pond rock pile on May 15,
1952, and was recaptured there on June 2 and June 4. In general, skinks
transferred from their original location seem soon to settle down in a
new range if the habitat is favorable, but establishment of a home range
may or may not be preceded by an initial period of wandering.
