>1. A flyer's normal range is 40 acres.
>2. Males tend to roam the range and females stay

>3. In scarse food years, more male pups are produced.
>4. In abundant food years, more female pups are

>1. He set up a sand box and the flyers buried nuts.

>Conclusion was that flyers use memory in recovery
