This talk by retired wildlife tour guide Paul Rogers, looks at the mammals preparing for winter, such as Grizzlies and Black Bears, the rutting season for the Elk and the effects of the wolf introduction in the parks. Birds are also starting their migration to warmer climes. Moose are feeding in the wet meadows, at this time full of spectacular autumn colours. Fast flowing rivers attract otters, ducks and geese. As well as the wonderful wildlife there are hundreds of hot springs, steaming pools and erupting geysers including Old Faithfull. This southern end of the Rockies is spectacular for its scenery, its wildlife and its colours.
