In this pic, you can see two babies ( on the top) clearly have tail feathers.

I took this pic below, tonight, I call this the Finch Kabob.. LOL
But you can clearly see, no tail feathers on the babies. ( the two with tails are mom and dad)

I never realized when they fledged that they actually had tail feathers, until I looked back at the pics.
Is this part of the baby bird growth process? They dont have any trouble flying without tails thats for sure!
