                        LOCAL BIRD MOVIE

Do you want to learn to watch birds? If so click on the movie just below this box, "Wings Over Our Two Counties". It will get you started, and all in the context of our own Stanislaus/Merced counties area. Or, just watch it for the pretty pictures, as well as Jim Gain's slide show just below it.

Field Trip Information Updated 11/3/18

Sunday, November 11 & Sunday December 30, San Joaquin River National Wildlife Refuge. Please note these trips are NOT scheduled for the third Sunday of the month. This refuge near Modesto offers diverse habitats, including mixed species transitional areas, riparian forest, oak wood-lands, grassland, and seasonal wetlands. Meet at the Stanislaus County Library parking lot (1500 I Street, Modesto) at 7:00 a.m. We will return to Modesto mid-afternoon. Trip leader: Ralph Baker, SASFieldTrips@yahoo.com . The December refuge trip will coincide with, and be a part of, the Caswell/Westley Christmas Bird Count.

I am sorry to say that, due to other commitments and the holidays, I will not be able to offer Saturday refuge trips beginning in November as promised. I will, however, try to offer a Saturday trip to the refuge in January.

Saturday, December 8, Merced National Wildlife Refuge.  This auto route tour gives birders an opportunity to see many species of waterfowl returning to the San Joaquin Valley for the winter.  There are also a few trails where we may encounter some passerine species.  Trip leader, Sal Salerno (bees2@sbcglobal.net) will meet participants at the Stanislaus Library parking lot (1500 I Street) at 7:00 a.m.  Carpooling is encouraged.  Bring lunch, binoculars, field guide, and insect repellent.  Participants will return to Modesto in mid-afternoon.  R.S.V.P. is not necessary, but helpful.

As of October 25, 2016, the second edition of "The Birding Sites of Stanislaus and Merced Counties" is currently available. This new edition contains many rare or uncommon birds found since 2011.  Three new trails have been added, and a few birding sites were deleted or updated.  Eight new species of birds that were accepted as Stanislaus County records have been included, as well.  In addition, new photographs of birds have been added to the 96-page edition. For information on where to obtain the birding booklet, contact any member of the Board of Governors of S.A.S.  


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.
