Bat Activity Trends
A Woodland Park Zoo Community Science Program
EVENTS
Bat Activity Trends (BAT)
The Bat Activity Trends (BAT) program involves going out to observe bats, right in your own neighborhood. You can participate from a yard, patio, balcony or even a window with a clear view of the sky!
Community Science For Bats!
Thursday September 4, 2025 | 7:00 PM – 9:00 PM
Green Lake, 7312 West Green Lake Drive NorthSeattle, WA, 98103 (map)
Join Bats Northwest and Woodland Park Zoo to collect bat data at Green Lake in Seattle. Community scientists (like you!) will help collect important data about where bats are and aren’t living in the city. We will teach you how to count bat activity (which involves leisurely watching the summer sky for 30 mintues after sunset), and we will capture bat sound recordings to share with you! Registration will be required for this event and a sign up form is forthcoming – for now mark your calendar!
The sun sets at 7:42pm so hopefully the Green Lake sky will have some bats flying above us. Look for volunteers at the Seattle Public Theater Bath house near Green Lake’s or our Bats Northwest signage and table just northwest of the Bathhouse (this program lasts 1.5-2 hours depending on the weather and the bats). Please bring your own chairs, if you would like to sit during the event.
Events cancel when it is raining hard.
