Our Mission
The mission of the Arroyo Colorado Audubon Society of Harlingen, Texas is to promote an understanding of the unique and important natural habitats of the Lower Rio Grande Valley, the birds and other wildlife they support, and their benefits to humans.
Membership Benefits
Speaker Socials with top birding personalities in the Rio Grande Valley. Field trips to out of the ordinary birding spots, many to private lands not usually accessible by the public. Other benefits of membership in ACAS include the quarterly Kiskadee Newsletter mailed to your address or emailed, emailed reminders of meetings and field trips, and listing on the website under Who We Are - or a printed copy of the ACAS Membership Directory. Meeting birders who are of a like mind and happy to bird with you is one of the major benefits of membership.
Speaker Social Meetings
The Arroyo Colorado Audubon Society meets in the Auditorium of the Harlingen Public Library on Jefferson and 76 Drive at 6:00 p.m. on the 2nd Thursday of each month, September to May. The general public is welcome free of charge.
Field Trips
Our organization sponsors a birding field trip to a local Valley “hot spot” area on the Saturday following the monthly membership meeting (Speaker Social) - September through May. Free to members, non-members - $5.00 donation. ACAS also sponsors guided bird walks in Ramsey Nature Park by request, email arroyocoloradoaudubon@gmail.com
