It’s been one year since orphaned moose calves Atlas, Luna, and Callisto first arrived at Northwest Trek Wildlife Park. And what an a-moose-ing year it’s been getting to know them and care for them!

The moose, all born in spring 2022, were rescued after being orphaned in Alaska. They arrived at Northwest Trek a few months later in August.

All three moose weighed under 200 pounds when they first arrived. Now, Atlas, the male calf, weighs over 734 pounds, and female calves Luna and Callisto weigh 664 pounds and 554 pounds. All three calves are nearly 5 feet tall at the shoulder. Moose are the tallest wild animals in North America, with adult males growing up to 1,200 pounds, 10.5 feet long, and 7.5 feet high.

“It’s been exciting to watch them grow and learn more every day,” said keeper Jordan, who helps care for the moose.

When the calves arrived, they were still dependent on milk and staff bottle-fed them daily.

Now, they eat a variety of leafy greens, moose chow, branches and browse.

All three are energetic and love the water. They can occasionally be spotted going for a swim in Horseshoe Lake.

“They splash around and even get the zoomies and run circles in the water,” said Jordan.

Moose are excellent swimmers and are known to be able to paddle through water at speeds of up to 6 miles per hour. Moose have a specially designed nose that acts as a built-in snorkel, allowing them to submerge underwater.
