Also seen are Canada geese, grebes, gulls, tundra swans, and American bitterns that nest there. In the spring and fall look for sandhill cranes in the western grassy meadows, or Bluebirds nesting in boxes along the approach road. This is closed from March 1 to July 1. Bighorn sheep, mule deer, coyotes, bald eagles, ospreys and the remnant of a wild horse herd live on this island. The mature forests of Douglas fir and ponderosa pine and flower-covered uplands also support goshawks, coyotes, marmots, mink and numerous songbirds.
Hiking trails lead to good viewing places.
At this 74-acre hatchery located along a beautiful spring creek, you can see up to a million rainbow and cutthroat trout and learn how they reproduce in captivity. The facility raises and produces eggs for propagation in stocked streams and lakes. Canada geese nest near the picnic area and the young can be seen in the summer. Keep an eye out for a glimpse of some of the large mammals found there seasonally including elk, deer, moose, and grizzly and black bears. The refuge lies at the southern end of Swan Lake.
