Sandia Crest

Sandia Crest, New Mexico


My fiancée and I decided to spend the Martin Luther King day weekend (Jan. 17-19th) observing the Rosy-finches at Sandia Crest New Mexico. Rosy-finches are birds of high mountains in western North America and eastern Asia. In North America, Rosy-finches primarily breed in alpine tundra above the timberline at high elevations. In the past ornithologists recognized just one species of Rosy-finch but now recognize four species, three of which occur in North America. Traditionally many birders had to travel to different regions to see these three species, but relatively recently birders discovered that all three species winter in the Sandia Mountains of northern New Mexico. Earlier this decade birders set up feeders at the Crest House, a restaurant and gift shop at the highest point in the Sandias (10,678 feet). Here birders can take a relatively easy drive (if the weather is nice) up into the mountains and see Rosy-finches coming right into a feeding station! In addition local birders and ornithologists began a banding program at Sandia Crest, which has expanded into looking at stable isotope data and now even radio tracking individual birds. Here are some of the photos I took at Sandia Crest.

















This is the most wide-spread of the three Rosy-finches in North America, the Gray-crowned Rosy-finch, which breeds in Mountainous areas of much of Northwest North America, stable isotope studies have shown Gray-crowned Rosy-finches wintering at Sandia Crest come down from as far away as Alaska















And here we have the most range restricted, the Brown-capped Rosy-finch; breeding mostly in Colorado small portions of adjacent Wyoming, Utah and New Mexico, this species is one of only a handful of species entirely endemic to the United States







Here is the Black Rosy-finch this species breeds in much of the middle Rocky Mountains, in Utah Wyoming, Idaho and Southern Montana, stable isotope studies have shown that the majority of Black Rosies wintering at Sandia Crest breed in a small area of northern Utah, this is also a United States endemic



Here are some pics from the rosy-finch banding

Here all three species of Rosy-finch feed on the deck of the Crest house. Hopefully the information gleaned from the Rosy-finch banding project will aid in the conservation of these beautiful mountain wanderes!
