Birding Sonora

Sonora is one of the 31 federal states of Mexico and is located in the northwest of the country.

Sonora’s shores are washed by the Sea of Cortez in the Gulf of California, which is connected to the Pacific Ocean further south. Sonora is thus linked to the so-called “Pacific Rim,” which offers ample opportunities for economic development as well as many challenges and opportunities for sustainable use of its natural resources. The Sonoran coastline is 1,208 km long.Sonora borders the state of Chihuahua to the east, Sinaloa to the south and Baja California to the northwest; to the north it shares an extensive border with the U.S. state of Arizona and a shorter one with New Mexico. To its west lies the Gulf of California; the state of Baja California Sur also shares a maritime boundary with Sonora.

The border with Chihuahua is 592 km, and the border with Sinaloa is 117 km. Sonora’s border with Arizona is 568 km long, and its border with New Mexico is 20 km long; these borders allow for multiple economic, cultural, and political ties with the United States. The state’s total perimeter is 2,505 km. Sonora is the second largest state in Mexico (184,934 km²), representing 9.2% of the nation’s total area. Sonora consists of four physiographic regions: The Sierra Madre Occidental, Parallel Mountains and Valleys, the Sonoran Desert, and the Coast of the Gulf of California. Sonora is located in a climactic strip in the northern hemisphere that has formed various deserts around the globe. The state is located at the same latitude as the deserts of North Africa, the Arabian Peninsula, and other regions.

    We were fortunate enough to have inherited a lot of information about the avi-fauna that exists in southern Sonora. A long history of ornithological explorations had ventured into the area to study what was here. More recently, Alamos has become a very popular destination for recreational birders from the USA looking to venture out of the ABA area.
