Based in southern New Mexico, our main activities are in Las Cruces in Dona Ana County, with frequent field trips to our neighbors in Sierra, Otero and Luna Counties in New Mexico, and El Paso County in Texas.  Birding areas include at least a dozen "Hotspots" within the city of Las Cruces and multiple ones along the Rio Grande, with the Mesilla Valley Bosque State Park and Leasburg Dam State Park being exceptional areas.  To the east of the Rio Grande and City of Las Cruces, the Organ Mountains (home of the newly formed Organ Mountains-Desert Peaks National Monument) offer an entirely different habitat that is home to a very different range of bird species.  It is a great place to be a birder.
