Organized in 1975, SAS is a chapter of the National Audubon Society – a world wide environmental oganization. SAS’s membership consists of National Audubon Society members living in Benton, Carroll, Clinton, Tippecanoe, Warren, and White counties. Membership in the National Audubon Society and residence in one of those counties automatically involves membership in SAS. With over 500 members, the Sycamore Audubon Society is the largest environmental group in mid-north Indiana. The chapter is named for a race of the Yellow-throated Warbler (Setophaga dominicus) which nests in sycamore trees along Indiana’s waterways, and is thus called the “Sycamore” Warbler.
