Three Rivers Audubon Society will hold a field trip to Lake Ouachita State Park, where participants will board a tour boat to Bird Island to observe purple martins, along with egrets, herons and ibises as they fly in to roost for the night.
The trip will be Aug. 16 and the boat will depart at 7 p.m. The cost is $9 for adults, $5 for children 6 to 12 years of age, and free for children under 6 years of age. This can be paid at the marina.
Tour boat reservations must be made at geoff.wright @arkansas.gov or by calling Claire Holmes at 870-534-2083.
Travel plans will be announced later.
