Welcome to the Black Canyon Audubon Society

Black Canyon Audubon Society was formed in 1990 and is one of 11 National Audubon Society chapters in Colorado. The BCAS is committed to the conservation of natural resources through our birding, conservation, and educational activities. The region covered by the Black Canyon Audubon society encompasses nearly 8,300 square miles and includes Delta, Gunnison, Hinsdale, Montrose, San Miguel and Ouray counties. Within this region, elevations vary from 4,695 to 14,309 feet above sea level. Rainfall ranges from less than 8 inches per year in the lower valleys to more than 50 on the higher peaks. Vegetation varies from desert scrub to boreal forest and alpine tundra.

Chapter Goals

  • 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 Gunnison Sage Grouse (GUSG) through joint efforts with GUSG working groups and federal and state agencies.

Volunteers Needed for the Birdhouse Display at the 2017 Montrose County Fair

If you have time to donate a couple of hours or more, we could sure use your help at the birdhouse display from July 21-29 at the Montrose County Fair.  We are trying to have someone at the display every day from 9-6.   Volunteers meet fair visitors, talk to them about the display and BCAS, and encourage them to bid on birdhouses during the ongoing silent auction.  Set up will be on the first day (Friday July 21) and take down will be the afternoon of Saturday July 29.  The Silent Auction goes on throughout the week and concludes at 1:00 on the final Saturday.  Help in collecting money and distributing birdhouses at the conclusion of the auction is particularly needed.

It really is quite fun being at the display!  It is eye-catching with many different types of birdhouses in a variety of imaginative styles.  The local Woodworkers Guild builds most of the birdhouses and donates them to BCAS for the silent auction.  Alpine Lumber donates prize money for winners of judging of the birdhouses.

Nearly all time slots are available!  Please call Jon Horn at (970) 209-5404 or email him at This email address is being protected from spambots. You need JavaScript enabled to view it.to let us know when you can come!
