Mountain lions, desert bighorn sheep, mule deer, and a variety of other wildlife live on and pass through the Nevada National Security Site each day. It’s a highly restricted area that is free of hunting and has surprisingly pristine areas.This 22-minute program highlights an extraordinary study on how mountain lions interact with their prey.

This video captures both the resident and anadromous forms of (Oncorhyncus mykiss) Rainbow Trout in a small tributary in the upper Cowlitz River Basin, Washington during spawning season. The male Rainbow Trout exhibits a courting behavior as it quivers against the side of the larger female (HOR) hatchery origin steelhead.

Scientists from the USGS Western Ecological Research Center (WERC) are conducting a "social attraction" study for seabirds in the Don Edwards San Francisco Bay National Wildlife Refuge. Historically, this region offered wetland habitats to local wildlife. With the introduction of industrial salt ponds and human development, however, much of this habitat was lost.

The USGS field tested the use of a portable hand-held kit for the detection of the environmental DNA (eDNA) of Asian carps (bighead carp and silver carp) in water samples as part of on-going invasive species detection research. The goals of the USGS-led research are to develop a method and kit that can be used on-site to detect Asian carp eDNA within one hour.

This ridiculously cute video of baby Harlequin Ducks (Histrionicus histrionicus) shows their first day outside the egg (about 20 hours old). Scientists at Patuxent Wildlife Research Center are training ducks to respond to sounds — just like a hearing test given to kids during elementary school — to learn more about their ability to hear underwater.
