The Stanislaus Audubon Society was formed in 1973 when Merced & Stanislaus County members voted to separate from the San Joaquin Audubon Society Chapter.


The Stanislaus Audubon Society promotes the enjoyment, understanding, and protection of birds and other wildlife by engaging people of all ages in birding, education, and conservation. For more information please visit the Chapter Information Page.

San Joaquin Valley Bird Photographers Group

San Joaquin Valley Bird Photographers is a new wild bird photography group sponsored by the Stanislaus Audubon Society. The goals are to enjoy, share, educate, and discuss everything related to the birds, habitats, biology, ecology, ID, as well as gear, ethics, and conservation matters. Be good, kind, and thoughtful about the welfare of the birds, habitats, and each other. The "San Joaquin Valley", includes the flat lands and low foothills from Kern County in the south to the San Joaquin Delta in San Joaquin County.

The primary resource used for this group is Flickr. The San Joaquin Valley Bird Photographers Flickr Group, joined by invitation, is a place to share and discuss photos from the San Joaquin Valley Area. An active Flickr account is needed to join a Flickr group. If you don't already have a Flickr account, sign up for one for free at https://www.flickr.com/signup Once you have an account, send an email to jimgain58@gmail.com and request to be added to the group.


The Board of Directors is requesting donations from the members of our local Audubon chapter. One targeted need is for the A.J. Grayson Scholarship, given yearly to a promising student in Environmental Sciences at C.S.U. Stanislaus. The last of the $600 scholarships will be awarded in the spring of 2019. We hope to continue this scholarship for the next five years, at a cost of $3,000.

The second targeted need is to cover the printing and postage costs of The Valley Habitat. Even though membership dues to National Audubon can cover part of those costs, we are still mailing 400+ printed copies every two months, at an expense of approximately $2,500 per year. We also pay stipends for program presenters, and we have other outgoing costs as well.

If you wish to make a tax-deductible donation, please send a check to Stanislaus Audubon Society, P.O. Box 4012, Modesto, CA 95352. You will receive a receipt of acknowledgment.


The Modesto Ponds are open to birders only on the second Saturday of every month. You must make an appointment at least 5 days in advance by calling 209-342-4501 or (preferably) by emailing Patricia Becerra at pbecerra@modestogov.com AND Ben Koehler at bkoehler@modestogov.com. Upon receiving permission, you will meet the operator at the gate at 8:00 a.m. You will then fill out the Liability Release Form when you sign in, and then pick up a map which clearly identifies the areas open to the public. Speed limit is 25 mph. Do not cross any bridge with a vehicle. The hours of birding are 8:00 -3:00 p.m. The location of the facility is 7007 Jennings Road. The operator phone on Saturday is 209-652-8662.


On July 12, 2016, Stanislaus Audubon Society donated "Birds of the Pacific Slope" to the Vasche Library at California State University, Stanislaus. The two-volume set of Andrew Jackson Grayson's work, consisting of his biography, field notes, and 156 watercolor prints, is housed in Special Collections. Members of the public can view these volumes by calling Special Collections (209-664-6538) or Circulation Coordinator (209-664-6561) and making an appointment to see them.
