Prime Hook National Wildlife Refuge, 11978 Turkle Pond Road, Milton, released its schedule of events for the remainder of the year.

— An Evening at the Hook Lecture Series: Bats: 7-8 p.m. Oct. 12. A spokesperson from the Delaware Bat Spotters Project will talk about the creatures of the night, how they help people and how people can help them. The project recruits volunteers to adopt and monitor bat colonies during the maternal nesting season. They are currently in trouble because of white nose syndrome, a disease that has caused bat mortality. Tracking the population gives researchers information about how this disease can be controlled. Light refreshments will be provided beginning at 6:30 p.m. Must register: 684-8419.

— Birding field trips: 8-11 a.m. Oct. 26, Nov. 12 and Dec. 10. Led by volunteer birding guides, beginner and experienced bird watchers will observe and learn about the bird species frequenting the refuge at this time of year. Come prepared for the weather and expect to walk up to a mile. Bring binoculars, a field guide and spotting scope. Binoculars will be available to borrow. Meet at the refuge office. Must register: 684-8419.
