How Do You Study Flying Squirrels?
Unlike humans, who respond to phone calls and fill out forms, flying squirrels are a bit more difficult to survey. To study how many flying squirrels are in the forest and how they are being born and are surviving from one year to the next you have to conduct a trapping study. By trapping certain areas year after year we have an idea of how many flying squirrels are surviving, being born and dying due to old age or from predators. When we visit an area we catch as many of the flying squirrels as we can, mark them with ear tags and then release them. From the number of marked squirrels we catch again compared to the unmarked flying squirrels you can estimate the total number of squirrels in the area.
