Keep track of our Daily Hawk Count >>

During the autumn months, our teams of volunteer hawk counters identify and tally 19 species of birds of prey, working under the leadership of an experienced dayleader.

Hawks are counted systematically using a repeatable method, called the Quadrant System, so that data from different years can be compared. The count results help us look for trends and patterns in hawk populations over time.

You can be a GGRO hawkwatcher! We recruit new hawkwatchers every spring, with trainings beginning in July. Volunteers must be able to commit to one regular day every two weeks between mid-August through early December; all training is provided. Volunteer activities take place in the Marin Headlands.

Age, Skills, What to Bring:

The best migration viewing is on fog-free days 10 am–2 pm, from September through November.

Hawk Hill has its own weather. What’s happening in your Bay Area neighborhood may bear no resemblance to the weather conditions on the hill. Bring more clothes than you think you will need!

Some essentials to bring, depending on weather, are: hat (for shade and/or warmth), windbreaker, insulation (wool, down, synthetic), gloves, sunglasses, sunscreen, and chapstick. Bring your own food and beverages. There are no food facilities in the Headlands, though the Visitor Center has some snacks and drinks for sale. Please, no alcoholic beverages. Leashed dogs are allowed. Don’t forget binoculars and field guides!
