By the middle part of May the eaglets are probably 4 to 5 weeks old, and you can see in this photo they are starting to get their brown feathers from the top of their heads down through their back (known as the cloak). Their pinfeathers have also emerged (see image below) and their wings are growing at a rapid rate. They are a little past the halfway point in the nest.
They are probably disappointed that the adult did not bring back any grub, but pretty sure they are impressed with how it stuck the landing!
For an excellent overview of first four weeks of an eaglet’s life, please visit the blog section of the Raptor Resource Project and search for Eaglet Growth and Development.
The Raptor Resource Project specializes in the preservation of falcons, eagles, ospreys, hawks and owls, and they are responsible for the Decorah Eagles webcam out of Decorah, Iowa.
