- Fledglings are about the same size as adults, but often their plumage color is muted and similar to adult females.
- In some species, fledglings' tails are shorter than the adults' because the tail feathers are still growing.
- You can recognize Downy and other woodpecker fledglings by their fresh and dapper plumage, whereas that of the adults is worn and dusky from their repeated trips in and out of the nest hole.
- Chickadee fledglings follow their parents to the bird feeder and perch nearby as the parents go to get food. They either wait, looking like they are waiting to be served, or they call incessantly "teeship teeship" and flutter their wings until fed.
- After one to three weeks, the parents stop feeding their fledglings and may even peck at them if they persist in begging for food to get them to feed themselves.
