Event Date: Apr. 18, 2022

The spectacle of spring bird migration is on full display at Bear Divide, a narrow pass in the San Gabriel Mountains just outside of Los Angeles, and the Moore Lab is counting thousands of birds each spring morning as they pass over a low saddle in the mountains on their way north. With thousands of migrants funneling through a narrow divide, this is truly a unique biological phenomenon.

Led by Moore Lab's postdoc Dr. Ryan Terrill, we began a regular count in 2021 to quantify the numbers and identities of birds migrating through Bear Divide. The data we collect will help us understand how well birds are doing as they respond to changing habitats and climates. Follow along at for live data and updates.

Come by and check out the spectacle! Let us know if you'll be there, sign up on Eventbrite. (IMPORTANT NOTE: Driving directions are provided below in the "How to Get There" section. Please do not follow the map provided by Eventbrite.)

How to Get There

Set "Bear Divide Vista Picnic Site" (in the vicinity of Santa Clarita) as your destination, which will get you very close. The exact site location is a dirt parking area at 34.3605331, -118.3976486 (you can put these coordinates into Google Maps), a quarter-mile west of Bear Divide Picnic Site. The dirt parking area is just past the left turn for the US Forest Service Fire Station. There will be other cars parked there and people with binoculars milling about on the road. If you don't see that, you have not arrived yet. It will take at least 30 minutes to get there from most parts of west and north Los Angeles. The roads are narrow and curvy, and there can be fog on the road in the morning hours.

Please note there are no indoor restrooms in this area, but lots of nature. Although we will largely stay in one place: bring water, athletic shoes, a sweatshirt, and a snack. We will have some pairs of binoculars, but please bring your own, if you have them.
