Backyard Bats: Bat and Hummingbird Feeder Study
Volunteers are needed for a hummingbird feeder monitoring study. Participation by households throughout southern Arizona is encouraged to determine the presence of lesser long-nosed bats. It’s easy and interesting to volunteer on this citizen science project!
- Monitor your feeder two or three times per week beginning in June and continuing until the bats leave, measuring the level of fluid in the feeder just before it gets dark and again when you rise in the morning
- Input your data on this website using the “Weekly Data Input Form” below. We will also ask you to fill out the “End of Season Summary Form” one time in the fall when the bats have begun their migration and stopped visiting your feeder.
- Additional information and detailed instructions can be found in the links below
If you would like to participate in this study, contact Emily Scobie at escobie@azgfd.gov
