TIME BUDGETS, ACTIVITY PERIODS, AND BEHAVIOR OF MEXICAN FOX SQUIRRELS

Time Budgets and Behavior of Nesting Bald

Time budgets for adult Bald Eagle (Haliaeetus leucocephalus) activities at nests were documented from mid-incubation to fledging at one nest and from hatching into the postfledging period at two nests. Time-lapse cameras recorded instantaneous samples of activity at 90 second intervals. Both sexes incubated eggs and brooded young. Eggs were incubated for 95% of daylight hours, with the female a...

Daily Activity and Nest Occupation Patterns of Fox Squirrels (Sciurus niger) throughout the Year.

The authors investigated the general activity and nest occupation patterns of fox squirrels in a natural setting using temperature-sensitive data loggers that measure activity as changes in the microenvironment of the animal. Data were obtained from 25 distinct preparations, upon 14 unique squirrels, totaling 1385 recording days. The animals were clearly diurnal, with a predominantly unimodal a...

Mechanisms of Cache Decision Making in Fox Squirrels (sciurus Niger)

The cache decisions of scatter-hoarding animals are influenced by a number of factors, including satiety, food quality, number of competitors, and the risk of predation and pilferage. However, it is unknown how animals assess these variables. We investigated this process experimentally in free-ranging fox squirrels (Sciurus niger) by measuring the effects of nut characteristics and social conte...
