Welcome to the
Black Canyon Audubon Society
Black Canyon Audubon Society was formed in 1990 and is one of eleven National Audubon Society chapters in Colorado. We are committed to the conservation of natural resources through our birding, conservation and educational activities.
- To promote the conservation of natural resources through informative public programs, our newsletter and this web site.
- To provide the opportunity for the observation and study of birds and other wildlife, through our field trips.
- To offer early education programs including bird banding stations and classroom bird skin programs.
- To empower our members and the public with the knowledge to be effective environmental advocates.
- To contribute to the recovery of the the Gunnison Sage Grouse (GUSG) through through joint efforts with GUSG working groups and federal and state agencies.
The region covered by the Black Canyon Audubon society consists of Delta, Gunnison, Hinsdale, Montrose, San Miguel and Ouray Counties. It encompasses nearly 8300 square miles, an area slightly larger than the state of New Jersey.
Within this region, elevations vary from 4,695 to 14,309 feet above sea level. Rainfall ranges from less than eight inches per year in the lower valleys to more than fifty on the higher peaks. Vegetation varies from desert scrub to boreal forest and alpine tundra.
Presentation at Bill Heddles Recreation Center
Birds, Animals, Plants, Geology, and Fossils of the Colorado River Delta in Mexico
September 25, 2014 at 7:00 p.m.
On September 25, the Black Canyon Audubon Society is sponsoring a PowerPoint presentation by Dave Sussman on the area in Mexico where the Colorado River enters the Gulf of California. Dave and his family have lived in Yuma, Arizona for the last 40 years and have visited the beaches and surrounding areas of the delta, only 100 miles south of their home, innumerable times. They have also been involved in paleontologic research there, in association with Arizona Western College in Yuma, the Page Museum in Los Angeles, and the government of Mexico. Dave and his wife now escape the Arizona summers by moving to their home on Redlands Mesa outside of Hotchkiss during the hottest months. The discussion will cover aspects of the geology, plants, and animals of the area, as well as a summary of the million-year-old fossils discovered there over the last 15 years. The presentation begins at 7PM at the Bill Heddles Recreation Center in Delta. The program is open to everyone and is free of charge.
Yellow-Billed Cuckoo Information
the US Fish and Wildlife Service is proposing to list the western population of the yellow-billed cuckoo as an endangered species. Three units of habitat in the BCAS area are under consideration: the North Fork of the Gunnison River in Delta County, the Gunnison River in Gunnison County, and the Uncompahgre River in Delta, Montrose, and Ouray counties. Click on the links below to see maps of these units. The critical habitats all appear to be the floodplains of these rivers that are well covered with trees.
This is copied directly from the USFWS information page about the potential listing:
Critical habitat is a term in the Endangered Species Act (ESA) that identifies geographic areas containing features essential for the conservation of a threatened or endangered species, and which may require special management considerations or protection. Designation of critical habitat does not affect land ownership or establish a refuge or preserve, and has no impact on private landowners taking actions on their land that do not require federal funding or permits.
On October 3, 2013, the Service proposed to list the western DPS of the yellow-billed cuckoo as a threatened species under the ESA in the western United States, Canada and Mexico. The listing proposal, which is based on the best scientific data available, cites threats from loss of riparian habitat and habitat fragmentation as a result of conversion of land to agriculture, dams and river flow management, bank protection, overgrazing and competition from exotic plants as key factors in the decline of the western yellow-billed cuckoo.
The Service is seeking information concerning the western yellow-billed cuckoo’s biology and habitat, threats to the species and current efforts to protect the bird. The Service also seeks information on the incremental economic effects of the proposed critical habitat designation.
Comments on the proposed critical habitat rule will be accepted through October 14, 2014. Comments may be submitted online at the Federal eRulemaking Portal at http://www.regulations.gov. The docket number for the proposed rule is FWS–R8–ES–2013-0011. Comments can also be sent by U.S. Mail or Hand Delivery: Public Comments Processing, Attn: FWS–ES–R8–2013–0011; Division of Policy and Directives Management; U.S. Fish and Wildlife Service; U.S. Fish & Wildlife Headquarters, MS: BPHC, 5275 Leesburg Pike, Falls Church, VA 22041-3803.
