Red knot (Calidris canutus), a candidate species for listing due to a rapid decline in population. The bird is dependent on one food during it’s northward migration: horseshoe crab eggs. Overfishing of the crabs has led a dramatic the decline of both knots and crabs. This bird was captured as part of a banding study by the Delaware Bay Shorebird Project.

Hibernating Arctic ground squirrels (Spermopilus parryii) at the University of Alaska at Fairbanks. This animal is the grand champion of all hibernators. It’s the only mammal that can drop its body temperature to below freezing. They hibernate for seven months. Females go in first, in August. Males follow a month later. They come out again to feed on tundra plants in May. Biologists at UAF have been studying the animal for 20 years, but still can’t figure out how this animal maintains a flat body temperature for all those months just above freezing. “You could put people into hibernation for space trips if you could understand it better,” said Franziska ‘Fran’ Kohl, one of the biologists here. “They also show symptoms of Alzheimers during hibernation.” She added that traumatic head injuries heal when in hibernation, another thing scientists are trying to figure out.

Researchers use binoculars to search for peregrine falcon chicks along the Colville River. The researchers band the chicks in order to track what habitat the birds are using repeatedly and how old the birds are when they return to the nest.
