Golden eagles are among the largest birds in North America. With wingspans of 6-7 ½ feet, they soar easily on warm air currents. When hunting, they fly close to the ground, flushing out small mammals such as ground squirrels and rabbits.
The nearby Diablo Range is home to one of the highest concentrations of wintering golden eagles ever recorded!
Our resident golden eagle, named Topaz after the Lake near where she was found, came to the museum in December 2005 with a wing injury that prevents sustained flight.
Female eagles are larger than males. We determined that Topaz is a female based her size (an average of 11 pounds!), and she confirmed that when she laid an egg.
