Conservation
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.
Conservation
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.
Conservation
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.
Conservation
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?
Conservation
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?
