“To form a perfect conception of the beauty and elegance of these Swans, you must observe them when they are not aware of your proximity, and as they glide over the waters of some secluded inland pond. On such occasions, the neck, which at other times is held stiffly upright, moves in graceful curves, now bent forward, now inclined backwards over the body. Now with an extended scooping movement the head becomes immersed for a moment, and with a sudden effort a flood of water is thrown over the back and wings, when it is seen rolling off in sparkling globules, like so many large pearls. The bird then shakes its wings, beats the water, and as if giddy with delight shoots away, gliding over and beneath the surface of the liquid element with surprising agility and grace. Imagine, reader, that a flock of fifty Swans are thus sporting before you, as they have more than once been in my sight, and you will feel, as I have felt, more happy and void of care than I can describe.”

Over 150 years ago, John James Audubon wrote about the awe inspired by watching trumpeter swans as they go about their business, untroubled by the doings of humans. Thanks to the determined efforts of conservationists across North America, future generations will continue to be mesmerized by these impressive birds. Read more

Nature is surprising.  And the more you explore and learn about the critters around us and their habitats, the more amazing the world seems!

The prairie vole is inconspicuous, but leads a fascinating life.

The prairie vole is a small, mouse-like animal that is only about 5 inches long and can be found in prairies and old fields in the southwest corner of Michigan. They prefer thick, grassy vegetation where they create highways under the grass. These networks of “roads” protect them from predators, give them access to multiple living chambers, and allow them to travel around their home territory gathering seeds, acorns, fruit, grains, and forbs to eat. They will cache (or store) food in underground chambers that can hold up to 4 liters of food – that’s almost a gallon of food for a critter only 5 inches long! Read more

Through generous support from DTE Energy, the DNR is celebrating the 40^th anniversary of Michigan’s Endangered Species Act from now through September. Each week, an important species will be featured.

Peregrine falcons are the fastest-flying birds in the world, reaching speeds of 200 miles per hour in a dive. Powerful and fierce, the peregrine falcon hunts small and medium-sized birds, dropping down on them from high above. Distinguishable by their dark brown backs and white faces with a black tear on their cheeks, these regal raptors can be seen on cliffs in the Upper Peninsula and in cities across the state.

Peregrine falcons are currently endangered in Michigan. They were included on the first list of endangered species created under Michigan’s Endangered Species Act. Pesticides took their toll on this bird of prey, and they were virtually eradicated from eastern North America by the middle of the 20th century.

After World War II, the use of a new insecticide known as DDT increased. Small birds and mammals accumulated the pesticide in their bodies. Raptors feeding on the contaminated birds and rodents were, in turn, poisoned by a progressive build-up of the pesticide. DDT was especially harmful to birds because it caused eggshell thinning, which resulted in weak eggs that broke under pressure.

After significant recovery efforts, peregrine falcons have made an incredible rebound and are now regularly seen in many large cities and coastal areas. In 2012, there were 12 confirmed nesting pairs in Michigan!
