The Southeastern Arizona Bird Observatory (SABO) is a nonprofit membership-supported scientific and educational organization founded in 1996 in Bisbee, Arizona, USA. The mission of the Southeastern Arizona Bird Observatory is to promote the conservation of the birds of southeastern Arizona, their habitats, and the diversity of species that share those habitats through research, monitoring, and public education. The observatory's founders are Tom Wood and Sheri Williamson, former managers of The Nature Conservancy's Ramsey Canyon Preserve.
Southeastern Arizona is at a biogeographic crossroads, where the Rocky Mountains meet the Sierra Madre Occidental of Mexico and the Chihuahuan Desert blends into the Sonoran Desert. Isolated mountain ranges known as "sky islands" are home to a variety of animal and plant species found nowhere else in the United States. The San Pedro River flows north from the mountains of northern Sonora, Mexico providing a highway for millions of migrating birds every spring and fall. The Santa Cruz River and Sonoita Creek also provide riparian habitat for breeding and migrating birds and other wildlife. Much of the best remaining wildlife habitat in the region is in the Coronado National Forest, national and state parks, national wildlife refuges and conservation areas, state wildlife areas, military reservations, and Nature Conservancy preserves.
The Southeastern Arizona Bird Observatory has conducted various monitoring projects both independently and in cooperation with public agencies. Its longest-running research project, in cooperation with the United States Bureau of Land Management and Friends of the San Pedro River, is a study of the hummingbirds that use the San Pedro River as a migratory corridor or breeding area. [1] [2] Banding sessions are open to the public, which has allowed thousands of visitors to observe research in progress and learn more about hummingbirds, other migratory birds, the ecological significance of the San Pedro River, and other conservation issues. Past projects include migration monitoring and breeding bird monitoring under the MAPS (Monitoring Avian Productivity and Survivorship) Program [3] for the National Park Service and Fish & Wildlife Service. SABO is a past participant in the Landbird Monitoring Network of the Americas. [4] [5]
Southeastern Arizona consistently ranks as one of the top five birding locations in the United States. Tens of thousands of birders visit the area each year, making nature-based tourism an important asset to the regional economy. The area's natural attractions also lure active retirees and others interested in relocating to areas with diverse opportunities for outdoor recreation. To cultivate environmental awareness and advocacy among both residents and tourists, the Southeastern Arizona Bird Observatory offers bird walks, workshops, other educational activities in both Arizona and northwestern Mexico, [6] and volunteer opportunities.
In November 2020, SABO assumed ownership and management of Ash Canyon Bird Sanctuary, on the southeastern slope of the Huachuca Mountains in Sierra Vista Southeast in southwestern Cochise County, Arizona. Purchase of the property, former home of the late Mary Jo Ballator, was accomplished through a single donation. The site is managed by SABO staff and volunteers; operations are funded through memberships and site-specific donations. The sanctuary is best known for its pollinator gardens and bird feeding stations, which are open to the public. The property lies in the transition zone (ecotone) between desert grassland and Madrean pine–oak woodlands and includes portions of a ciénega, a rare wetland type unique to the arid regions of the southwestern United States and northern Mexico. Over 200 species of birds have been recorded at the site, including lucifer sheartail, plain-capped starthroat, elegant trogon, Montezuma quail, and rufous-winged sparrow. Sightings contributed to iNaturalist have recorded over 240 non-bird species, including over 180 species of arthropods.
The Southeastern Arizona Bird Observatory also supports community-based outreach and economic development programs such as the Southwest Wings Birding and Nature Festival, the Wings Over Willcox Sandhill Crane Celebration, and the Southeastern Arizona Birding Trail.
Sierra Vista is a city in Cochise County, Arizona, United States. According to the 2020 Census, the population of the city is 45,308, and is the 27th most populous city in Arizona. The city is part of the Sierra Vista-Douglas Metropolitan Area, with a 2010 population of 131,346. Fort Huachuca, a U.S. Army post, has been incorporated and is located in the northwest part of the city. Sierra Vista is bordered by the cities of Huachuca City and Whetstone to the north and Sierra Vista Southeast to the South.
The Chihuahuan Desert is a desert and ecoregion designation covering parts of northern Mexico and the southwestern United States. It occupies much of West Texas, the middle and lower Rio Grande Valley, the lower Pecos Valley in New Mexico, and a portion of southeastern Arizona, as well as the central and northern portions of the Mexican Plateau. It is bordered on the west by the Sonoran Desert and the extensive Sierra Madre Occidental range, along with northwestern lowlands of the Sierra Madre Oriental range. On the Mexican side, it covers a large portion of the state of Chihuahua, along with portions of Coahuila, north-eastern Durango, the extreme northern part of Zacatecas, and small western portions of Nuevo León. With an area of about 501,896 km2 (193,783 sq mi), it is the largest desert in North America.
Sierra de San Pedro Mártir is a mountain range located within southern Ensenada Municipality and southern Baja California state, of northwestern Mexico.
Sky islands are isolated mountains surrounded by radically different lowland environments. The term originally referred to those found on the Mexican Plateau, and has extended to similarly isolated high-altitude forests. The isolation has significant implications for these natural habitats. The American Southwest region began warming up between ∼20,000–10,000 years BP and atmospheric temperatures increased substantially, resulting in the formation of vast deserts that isolated the sky islands. Endemism, altitudinal migration, and relict populations are some of the natural phenomena to be found on sky islands.
Monte Vista National Wildlife Refuge is a United States National Wildlife Refuge located in southern Colorado. The refuge is located in the San Luis Valley south of the town of Monte Vista, Colorado in southeastern Rio Grande County, Colorado, in the watershed of the Rio Grande. It was established in 1953 by the Migratory Bird Conservation Commission to provide a habitat for wildlife, particularly waterfowl, in the San Luis Valley.
The blue-throated mountaingem, also known as the blue-throated mountain-gem or blue-throated hummingbird is a species of hummingbird in tribe Lampornithini of subfamily Trochilinae. It is found in Mexico and the United States.
The Sierra Madre Occidental pine–oak forests are a Temperate broadleaf and mixed forests ecoregion of the Sierra Madre Occidental range from the southwest USA region to the western part of Mexico. They are home to a large number of endemic plants and important habitat for wildlife.
Aridoamerica denotes an ecological region spanning Northern Mexico and the Southwestern United States, defined by the presence of the culturally significant staple foodstuff Phaseolus acutifolius, a drought-resistant bean. Its dry, arid climate and geography stand in contrast to the verdant Mesoamerica of present-day central Mexico into Central America to the south and east, and the higher, milder "island" of Oasisamerica to the north. Aridoamerica overlaps with both.
The Pacific Flyway is a major north-south flyway for migratory birds in the Americas, extending from Alaska to Patagonia. Every year, migratory birds travel some or all of this distance both in spring and in fall, following food sources, heading to breeding grounds, or travelling to overwintering sites.
The lucifer sheartail or lucifer hummingbird is a medium-sized, 10 cm long, green hummingbird with a slightly curved bill and distinctive outward flare of its gorget feathers. Its habitat is in high-altitude areas of northern Mexico and southwestern United States. It winters in central Mexico.
The violet-crowned hummingbird is a medium-sized hummingbird. It is 10 cm long and weighs approximately 5 g.
The San Pedro River is a northward-flowing stream originating about 10 miles (16 km) south of the international border south of Sierra Vista, Arizona, in Cananea Municipality, Sonora, Mexico. The river starts at the confluence of other streams just east of Sauceda, Cananea. Within Arizona, the river flows 140 miles (230 km) north through Cochise County, Pima County, Graham County, and Pinal County to its confluence with the Gila River, at Winkelman, Arizona. It is the last major, undammed desert river in the American Southwest, and it is of major ecological importance as it hosts two-thirds of the avian diversity in the United States, including 100 species of breeding birds and almost 300 species of migrating birds.
The Institute for Bird Populations (IBP), based in Petaluma, California is a non-profit organization dedicated to studying and monitoring bird populations, and providing land managers and policy makers with information needed to better manage those populations.
The Huachuca Mountains are part of the Sierra Vista Ranger District of the Coronado National Forest in Cochise County in southeastern Arizona, approximately 70 miles (110 km) south-southeast of Tucson and southwest of the city of Sierra Vista.
