Use of Nest Boxes by Squirrels in the South Carolina Piedmont
Nest box use by gray squirrels (Sciurus carolinensis) and southern flying squirrels (Glaucomys volans) was studied in 2 isolated hardwood stands in the South Carolina Piedmont from December 1980 through December 1983. Over a 3-year period, an average of 94% of 100 boxes were used by squirrels. The number of squirrels occupying boxes increased (P < 0.001) over the 3-year period. Parturition dates and litter sizes were determined for 104 litters containing 283 squirrels. Two peaks of parturition occurred: 47% of the litters were born during January to March, and 46% were born during...
