It take a lot of work to learn to be a successful hawk. Youngsters have to learn the lessons of not only how to hunt, but what to hunt as well. This discrimination takes weeks and weeks of diligent practice but really takes about 6 months to perfect. And even then all it takes is 1 bad rat or pigeon to screw the whole thing up. During this time they will be trained by their parents on exactly where and what to hunt. I caught up with 2 female chicks running all over the Park doing some such stuff.
One flew down!
Then joined by a sibling.
They practiced killing earthworms.
Got some sun.
Then practiced killing each other.
Big sisters can be so pushy!
