SJV staff Robert Mesta, Carol Beardmore, and Jennie Duberstein, together with Rob Hazelwood of Region 6 USFWS, Dick Hutto and Fernando Villaseñor from the University of Montana, and Eduardo Gómez-Limón of Monte Sonorense, visited a number of different riparian sites during a five-day tour of Sonora. Areas visited included the Río Sonora, the Río Cocóspera, the Río Moctezuma, and the Río Matape. The trip was part of the Western North American Migratory Landbird Project.
In 2004, the Sonoran Joint Venture, the U.S. Fish and Wildlife Service, PPL Montana LLC, Inc., the University of Montana, the U.S. Geological Survey, and a group of diverse partners undertook an innovative international effort to bring together field research, on-the-ground conservation, and restoration activities to benefit breeding, migratory stopover, and wintering habitats of western North American Neotropical riparian bird species. With matching funds from two Neotropical Migratory Bird Conservation Act Grants, the project aims to protect birds by identifying, conserving, and restoring riparian forests that serve as critical habitat throughout western North America . It focuses on breeding bird populations along the Madison and Missouri River corridors in Montana , and wintering and migrating bird populations in Sonora , Mexico. Many of Montana 's birds are presumed to spend at least part of the winter in Sonora, and this study will help identify and protect important sites for these species. In the first year of this project, Sonoran biologists conducted bird surveys at over 600 points spread across nine major vegetation types throughout Sonora. This information will provide a solid foundation for deciding which habitats migrants (and residents) use in winter and the significance of riparian vegetation to these wintering birds. In total, biologists recorded 194 different species from point counts throughout the state of Sonora. In Montana , researchers implemented similar studies for breeding birds, including point-count and river surveys that focused on landbirds using both the river and habitat adjacent to the river system. The 310 point counts and 672 km river surveys yielded 136 different species. Researchers documented over 350 nesting attempts made by 19 open-cup nesting species, looking at riparian areas that differed in vegetation structure.
The ultimate goal of this project is to identify riparian areas important to Neotropical migrants and provide information to public and private land managers in the U.S. and Mexico. This will help them to identify high quality riparian forests in need of protection, to improve restoration and management of degraded sites, and to monitor the success of those efforts. The Nature Conservancy announces cross-border project to protect San Pedro River
Toward that goal, the Conservancy and its Mexican partners plan to establish a 10,000-acre preserve at a lush and biologically rich site, known as Rancho Los Fresnos, at the river’s key source south of the international border in northeastern Sonora, Mexico, near Sierra Vista, Arizona. The historic working ranch has been sensitively managed by the same family for generations. The ranch also anchors the largest ciénega, an isolated desert spring or marsh, remaining in the San Pedro River watershed area, and links to one of the largest and highest quality grassland valleys in a region spanning several states and Mexico.
The Nature Conservancy is working to assume joint management of Rancho Los Fresnos—with Mexican nonprofits Naturalia A.C. and Biodiversidad y Desarrollo Armónica (BIDA) and possibly other partners—by year-end. Funds for the $4.2 million project will be raised by the Conservancy through private and public sources primarily in the U.S. Madrean Pine-Oak Woodlands added to world list of 'hot spots'*
Madrean Pine-Oak Woodlands have been added to a short list of 34 places around the world where rich biological resources are at risk from environmental threats. These woodlands include Mexico's main mountain chains, namely the Sierra Madre Occidental, the Sierra Madre Oriental, the Trans-Mexican Volcanic Belt, the Sierra Madre del Sur, and the Sierra Norte de Oaxaca, as well as isolated mountaintop islands in Baja California (particularly around the Sierra de la Laguna). Although the vast majority of the hotspot's 461,265 km² lie within Mexico, a few scattered patches occur in the southern United States (represented by the Madrean Sky Islands, a series of about 40 mountain-tops in southern Arizona and New Mexico). A quarter of all Mexico's plant species are found here, many of them found nowhere else on Earth, as well as seven endemic and threatened bird species. Unfortunately, the destruction of pine forests due to excessive logging is the leading cause of habitat loss in this region.

New communication tool for environmental educators Marshbird training workshop The main objective of the workshop is to train participants to distinguish all of the calls of the Yuma Clapper Rail. A secondary objective will be to train participants to identify other marsh bird calls which could potentially be confused with clapper rails. For more details, contact Courtney Conway.
Resource for Partners: Migratory Bird & Wetland Newslink New radio program teaches about birds BirdNote shows are two-minute vignettes that incorporate the rich sounds of birds with stories that illustrate the interesting-and in some cases, truly amazing-abilities of birds. If you live in the Seattle area, BirdNote can be heard from 8:58-9:00am on KPLU 88.5 fm. For those of you outside of the listening area, BirdNote also has a website where you can listen to the show and more. BirdNote.org offers you resources to "dig deeper" into the world of birds, birding, and conservation. February 3, 2004 - $45,000 fine in eagle deaths. By Mitch Tobin. © Arizona Daily Star.
