Bull trout (Salvelinus confluentus) swimming in the Bighorn Creek, in the Wigwam River drainage in British Columbia. This is one of the last, best places for spawning of the vulnerable (ICUN) and federally-threatened bull trout, and is part of the Kootenay River system, which sees an annual migration of bull trout from Lake Koocanusa, some fifty miles away. The fish prefer very cold water of 40 degrees or so in order to spawn, and the springs in this area provide that. Ram Creek flows into the Wigwam, and between the two of them they support some 5,000 bull trout.

Millions of monarch butterflies (Danaus plexippus) roost on the Chincua Mountain near Angangueo, Mexico. This is one of five wintering roosts for monarchs, where the cool mountain climate slows their metabolism enough for them to overwinter before migrating back northward in the spring. Logging threatens this spectacle–Already one of the five sites is no longer used by the butterflies due to the forest being cleared.

Thousands of sandhill cranes roost on the Platte River during their annual migratory stopover at the Rowe Audubon Sanctuary near Gibbon, NE. With water in the river fully appropriated for urban areas and agriculture, many wonder how long it will be until the river runs dry. Some 600,000 to 800,000 cranes use just a few miles of the river in central Nebraska–areas that have been been mechanically cleared of the woody vegetation that the birds can’t tolerate.

Aerials of the Jonah Field in the Green River Basin, Wyoming. A once-wild area that’s now an industrial zone due to natural gas drilling. Sage grouse, mule deer and pronghorn antelope habitat has mostly been ruined here, with no end in sight as the drilling increases across the Pinedale Anticline, the large mesa that caps the gas deposits.

The snake pit at the 45th annual Mangum Rattlesnake Derby in Mangum, Oklahoma. This rattlesnake festival takes in between 1,500 and 2,000 pounds of western diamondback rattlesnakes (Crotalus atrox) each year. Some 30,000 people come here on the last weekend of April to see such things as a photo booth in which people can pose with a live rattler that’s been defanged and had its mouth stitched shut, a safari bus tour in which folks can pick up a live rattlesnake, a cafe serving rattlesnake meat, and a butcher shop.

A western diamondback rattlesnake (Crotalus atrox) in the foothills of the Wichita Mountains in Oklahoma. Studies are showing that rattlesnakes that have the genetic tendency to migrate are being killed in ever-increasing numbers on our nation’s roads, leaving those snakes with non-migrating tendencies behind to breed.
