Getting out into nature should be fun, accessible, and affordable. That’s why we’re here to help with a guide on how to plan and prepare for the most popular activity in the parks: day hiking.  

In the rough waters beneath the iconic Point Bonita Lighthouse sits a 180-million-year-old rock that geologists from all over the world travel to marvel at.

Tune into the livestream from Alcatraz to see the fledgling Peregrine Falcon family grow before your very eyes.  

A novel technique collecting songbird DNA from migratory raptors, and using DNA barcoding to identify prey species, helps quantify raptor diet during migration and track trends through time.

We don't know much about Broad-winged Hawks' migration along the Pacific Flyway, so GGRO volunteers tracked the journeys of five. Where did they go?

At GGRO, we observe that female raptors typically migrate before males and juveniles typically migrate before adults. How does this compare to findings at other observation stations?

Red-tailed Hawks are common raptors in the Bay Area, yet males and females can be difficult to tell apart. Researchers used DNA and small differences in size to better understand their migration.

Data from seven fall raptor migration sites show that not only have kestrel numbers have been declining across North America, they've also been getting smaller. 

Anticoagulant rodenticides (AR) are used to control pests, but secondary exposure can affect non-target species like raptors. Researchers tested juvenile Red-tailed Hawks to learn more.
