I have spent most of my life in Florida, but in 2011 I moved to Dolan Springs, in northwestern Arizona. Dolan Springs is surrounded by Bureau of Land Management land, including Mt. Tipton Wilderness Area, less than a mile from my home. A little further away there is Lake Meade Recreational Area and the west rim of the Grand Canyon. Eager to learn the plant and animal life on these diverse natural landscapes, this area became my class room and playground. In 2014 I began submitting bird checklist to eBird, and now this Dawn Chorus gives me an opportunity to report some of the observations made in this area.
The Mojave Desert covers approximately 50,000 square miles in parts of southern California, southern Nevada, northwestern Arizona and a small area in southwestern Utah (MacKay, P. 2003). The discussion in this Dawn Chorus covers a small part of this area in Desert Scrub habitat around Dolan Springs in northwestern Arizona. Desert scrub in this part of the Mojave can be found at elevations of 3,000 to 4,500 feet., from the desert floor to slightly higher alluvial fans and on to the foot hills of the Cerbat Mountains. The dominant vegetation is Creoste Bush (Larrea tridentata) and White Bursage (Ambrosia dumosa) at lower elevations, blending into Joshua Tree (Yucca brevifolia) habitat at the higher elevations. Other common plants in the scrub are several sages (Salvia spp), Brittlebush (Encelia farinosa), Mormon Tea (Ephedra viridis), Mojave Yucca (Yucca schidigera), thorn bush (Lycium spp.) and Cat-claw Acacia (Acacia greggii).
Dolan Springs is in Mohave County, AZ, and according to ebird records, 400 bird species have been reported. The county covers a diverse natural area, with mountains over 7,000 feet to low elevation sites along the Colorado River, including several large reservoirs. Data for this report were created by make an ebird patch using 12 locations that have been reported in complete checklist which occurred in desert scrub habitat. This ebird patch covered a period of 8 years, with 868 checklists resulting with 91 bird species.
