Common Buckeye


Pictured is the Common Buckeye. It is thought that the eyespots of the Common Buckeye Butterfly may be used to scare away predators. The Common Buckeye was featured on the 2006 United States Postal Service 24-cent postage stamp.

Viceroy



The viceroy butterfly is dark orange with black veins. A row of white spots edge its wings. Its color and pattern mimics the monarch butterfly's pattern except for a black horizontal stripe that crosses the bottom of its back wings. The viceroy caterpillar is white and olive-brown. The viceroy and monarch were once thought to exhibit Batesian mimicry where a harmless species mimics a toxic species. Studies conducted in the early 1990's suggest that the viceroy and the monarch are actually examples of Mullerian mimicry where two equally toxic species mimic each other to the benefit of each. Just goes to show you there's always something new to discover in the natural world!
The picture shown is two Viceroys in copula and was taken today in Coles County.

Coyote


The coyote is a member of the dog family. In size and shape the coyote is like a medium-sized Collie dog, but its tail is round and bushy and is carried straight out below the level of its back.
One of the most adaptable animals in the world, the coyote can change its breeding habits, diet and social dynamics to survive in a wide variety of habitats.
Alone, in pairs or in packs, coyotes maintain their territories by marking them with urine. They also use calls to defend this territory, as well as for strengthening social bonds and general communication. Coyotes can easily leap an 8 foot fence or wall. They have been spotted climbing over a 14 foot cyclone fence.
Environmentalists firmly believe that the coyotes are necessary to preserve the balance of nature. Some sportsmen feel the coyote is responsible for the declines in game species. Biologists agree that individual animals preying on livestock and poultry should be destroyed but that the species as a whole is not necessarily harmful, because much of its diet is made up of destructive rodents. Biologists also agree that coyote populations have no lasting effects on other wildlife populations. So the controversy rages on.

Red-tailed Hawk


The most common and widespread hawk in North America, the Red-tailed Hawk is a bird of open country. It is frequently seen sitting on utility poles where it watches for rodents in the grass along the roadsides. The hawk pictured is an immature bird and testimony to this was that he let me get quite close before he/she flew. Also notice the tail has not turned red yet.
