 This pack seem prepared to allow their young a brief foray to experience the world beyond their den 1.


 
Even in Yellow Stone it is extremely rare to see wolf pups like this.
 
Before long they are summoned back into the forest by the pack. It will be winter before they are regularly seen again.
 
As May turns to June, Yellow Stone sees its nursery season. 
 
By early June, summer is finally here. In the flower meadows, plants turn sunlight into the sugar of nectar, and that's what Yellow Stone's smallest migrating bird has been waiting for. The Calliope Hummingbird 2 has made the journey all the way from Mexico. He’ll make this flower patch his own. And he’ll fight to defend it. He’ll even take on a far larger Rufous Hummingbird.
