Here's a report from our land manager:
At three weeks+ old, the largest eaglet is nearing the one foot high growth mark. The smaller two are not too far behind. The webcam images are a little deceiving when it comes to gauging their size. The darker feathers we see coming in are the secondary down feathers. They are a little darker and thicker than the first down feathers. In another 2-3 weeks, we will start to see the darker juvenile body and flight feathers. As the adults move around the nest, you might have noticed it looks like their talons are curved into a ball. They do this to protect the young eaglets. The adult's talons are very sharp, and could easily injure one of the chicks if they are not careful. All three are eating well and growing fast.
