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.

Dear List,

I have 500 sites, and each site contains twelve transects.

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