Another week went by and I went back to check on the nest. What a difference a week makes. The baby had developed some wing feathers and was vigorously flapping them in the nest. This strengthens the wings and helps the baby learn about catching wind and lift. In the raptor world they call this wingersizing. There is still some white fuzz but a lot of pin feathers are showing up now.
