A USFWS wildlife biologist, runs a radio telemtery set for bobcat signals along the wall on the Lower Rio Grande NWR near Santa Maria. The wall bisects many of the tiny habitat tracts that remain along the border.
A bobcat (Lynx rufus) photographed by a camera trap along the Texas-Mexico border in Texas. Cutting in many places through the last of the habitat left along the lower Rio Grande river, the wall is a huge impediment to the movement of wildlife species that can’t fly over it.
