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.

Millions of monarch butterflies (Danaus plexippus) roost on the Sierra Chincua (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.

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.

Biologists track a handful of tagged fish daily to try and learn about their migratory movements, which a series of dams on the nearby Clark Fork River have severely impeded.

They will put tiny geolocators, which track sun intensity as well as sunrise and sunset, the birds’ backs. When the birds are recaptured (months from now) and the data is downloaded and used to calculate the birds’ migratory route. The species winters in South America, but little is known of its specific route.

Cowbirds (Molothrus sp.) that were caught in traps set for them at Fort Hood Army Base near Kileen, TX. Of these cowbirds, the females will be killed and the males will be kept to lure other birds. The eradication of cowbirds has been going on for awhile here in an effort to study the effect of their parasitism on endangered birds like the black-capped vireo and golden-cheeked warbler.

Thousands of sandhill cranes (Grus canadensis) 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.

Aerial of the marshlands that have literally been cut to pieces by pipeline canals and shipping channels that have been put in by the oil industry over the years. Such huge canals have allowed saltwater to intrude, killing off the marsh and eliminating its resistance to catastrophic events in the Gulf such as storms, and now, oil spills like the Deepwater Horizon.

Federally endangered Alabama beach mice (Peromyscus polionotus ammobates) are captured and measured as part of a population survey along the Fort Morgan Peninsula near Gulf Shores, Alabama. Houses and condos have inundated the area, with many more planned, eliminating more habitat yearly. Many more are planned. Besides development, feral cats pose a huge problem as well.
