Because the DV is a count, you should look at -xtmepoisson-, -xtpoisson-, or -xtnbreg-. Which you choose will depend in large part on the complexity of the model you want. -xtmepoisson- will allow multiple levels of nesting and random slopes and intercepts. The others are simpler models but possibly easier and more useful.

My dependent variable is the number of bats encountered along each transect
