For nearly 40 years, the Golden Gate Raptor Observatory at the Parks Conservancy has collaborated with the National Parks Service to track the migratory patterns of these birds – collectively known as raptors – with the mission of inspiring their preservation throughout California.

Data collected over the years has sought to identify and understand the biggest threats to raptor populations – with climate change being the largest. Changes in seasons and temperature can shift the relationships between plants and animal species, and have a large ripple effect on the food chains of many raptors.
