Golden Eagle

Although capable of killing large prey, golden eagles primarily hunt rabbits, hares, ground squirrels, and prairie dogs. It takes a juvenile bird four years to reach adulthood, juveniles typically don’t have territories and don’t migrate far from their natal territories (where they hatched). They disperse and ”hang around” the region for several years.

Northern Pintail

Pintails are a fast, long-distant migrant. Using satellite-tracking technology, the longest non-stop flight on record was 1,800 mi/2,900 km.

Eastern Collared Lizard

Eastern collared lizards are very alert—and very fast! They’re well adapted to running around their rocky habitats and jump among rocks easily. At top speeds, they run using only their back legs! They have highly powerful jaws capable of delivering a strong bite that can break the skin if captured.

Pawnee Montane Skipper

The Pawnee montane skipper habitat has been threatened by the proposed Two Forks dam and reservoir which would have inundated and destroyed 22% of the skipper’s habitat with an estimated loss of 23-42% of the population. Two large recent fires, Buffalo Creek Fire and Hayman Fire affected nearly half of the skipper habitat.

Two-spotted skipper

While worldwide the two-spotted skipper is secure, that is not necessarily the case on a local basis. Most states where the butterfly resides consider it fairly rare

Common Nighthawk

Male common nighthawks are known for their dramatic “booming” flight display. When flying above the trees, a male will dive towards the ground and abruptly pull out of the dive, sometimes just above the ground. As he flexes his wings downward, the air rushes across his wingtips, making a booming or whooshing sound. The male may dive to impress a female or scare intruders, such as people.

American Kestrel

Kestrels hide surplus prey in grass clumps, tree roots, bushes, fence posts, tree limbs, and cavities, to save the food for lean times or to hide it from thieves. In winter in many southern parts of the range, female and males use different habitats. Females use the typical open habitat, and males use areas with more trees. This situation appears to be the result of the females migrating south first and establishing winter territories, leaving males to the more wooded areas.

Dickcissel

Dickcissels gather in large flocks for fall and spring migration, up to thousands of birds. On their winter range, flocks may be as large as millions of birds, and these flocks can inflict substantial damage on agricultural crops in South America.

Poweshiek Skipperling

Poweshiek skipperling butterfly populations have shown a well-documented collapse in less than a decade between 2000 and 2010, with likely extirpation of over 95% of the populations. In 2000, Poweshiek skipperling was known from native prairie remnants in Iowa, Minnesota, North and South Dakota, and Wisconsin and in fens in Michigan. By 2010, it was no longer found in the Dakotas, Minnesota, and Iowa. The original core habitat range for the species was orders of magnitude larger than the current range. The cause of this wide-spread decline is still unknown.
