June Wildlife Whereabouts: Moose Calves, Fox Pups, and Spring Rains

Wildlife Whereabouts: Moose Calves, Fox Pups, and Spring Rains

Long days and warmer temperatures mark summer's arrival in Grand Teton National Park. As daily high temperatures rise with the season, mid-day animal activity will begin to reduce considerably. Early mornings or late afternoons are your best chance to see some of the park's incredible wildlife. 

  • June has seen above average rainfall statewide.  According to meteorologist Alan Smith (Buckrail), the first 3 weeks of June 2023 have been the wettest June since 2011!  
  • This year’s abundant spring rains have resulted in tremendous vegetation growth, particularly among grasses and forbs, which will benefit many species of wildlife.
  • Mosquitoes are now out in force (but vary in abundance across the landscape), providing food to birds, bats, fish, and other species.
  • Grizzly bear 399 is 27 years old this year and has 1 cub-of-the-year. She as well as other grizzly bears have commonly been observed from roadsides, so please drive slowly and be vigilant for wildlife at all times, particularly at dawn/dusk and after dark.  
  • Trumpeter swan eggs are hatching. Young swans, or cygnets, are typically light gray in color and can swim within 24 hours of hatching. They will be roughly three and a half to four months old before they take their first flight. 
  • The spring birth pulse for Jackson Hole ungulates (mammals with hooves) is winding down. Most ungulate babies are on their feet and able to move the day they are born. Some, like bison, use the follower strategy, where the new calves stay with their mothers at all times. Others, like deer, elk, and pronghorn, use the hider strategy, where mothers often hide their newborn fawns or calves and return to them periodically to nurse. 
  • Moose are VERY protective of their young. Please be cautious and give them a wide berth. 
  • Marmots, one of the largest mammals in the squirrel family, are active and feeding primarily in the morning and evening and rest during the heat of the day. 
  • Neotropical birds, such as ruby crowned kinglets, western tanagers, and hummingbirds, have returned and are busy breeding and raising young.  
  • Wolf, coyote, and fox pups from successfully reproducing packs or pairs have now emerged from their dens. They do not stray far from their dens, rendezvous sites, or the watchful eye of adults. They are out and about, learning about the new world around them while playing and growing rapidly.
