This is a diary of observations by naturalist/writer Ryden. This type of coverage can be interesting and enlightening, but Ryden is trying to pass it off as research. For example: Because there was no evidence of aspen by the pond, she assumes (wrongly) that these beavers have never tasted it, while beavers, in fact, do move beyond their home sites. Ryden is not satisfied to observe; she interferes, particularly when she feeds the beavers when she assumes that they need her help. Although this book's style may be entertaining to some, Better information can be obtained from wildlife magazines. Not recommended.
