Many of the large mammals have retreated to higher, cooler ground. The best time for wildlife viewing is early and late, in the cooler parts of the day. Pronghorn antelope make themselves scarce this time of the year, but early risers with a keen eye can spot them in Lamar Valley and the northeast portion of the park. Bull elk and moose are in full velvet, and many have been sighted recently. We have had several moose cow and calf sightings in unusual parts of Yellowstone.
Many bison are still visible in most or all parts of the park.
Wolf activity is still high in the Lamar Valley area for the patient watcher. One of the Osprey nests in the Tower area is occupied by young osprey waiting for their next meal. All other nests throughout the ecosystem also appear to have produced fledglings. One coyote was spotted stalking a Trumpeter Swan nest earlier in the spring. This was quite a sight as the Trumpeter Swan mate and several Canada Geese joined forces to protect the swan nest and push the coyote into retreat.
