Squirrels make their homes mostly above ground, in the trees (burt and grossenheider 1980, 119) these trees are providers of food as well as shelter some squirrels inhabit crevices in the tree itself and others build nests, made of leaves, in the branches. Ls 1 lab demo 1 13 january 2014 introduction: the broader context of this lab was aimed at observing animals and documenting specific animal behavior patterns.
They use burrows dug by prairie dogs, ground squirrels, badgers, marmots, skunks, armadillos, kangaroo rats, and tortoises both members of a pair enlarge and maintain the existing burrow by digging with their beaks and kicking back soil with their feet. On the attached graphs, n stands for none which means 0 squirrels were seen, p stands for present which means 1-3 squirrels were seen, and h stands for high which means 4 or more squirrels were seen we performed 7 chisquare tests on our data which is attached, and also we included 3 pages of our raw data that we collected.
