Wood-Pewee Fledged

I saw two of the three wood-pewee fledglings nearby along the river in a willow shrub. The parents were dashing by and feeding them in what seemed like a fraction of a second. This fledgling sat quietly on this small branch and patiently waited. I watched it for about a half an hour, and I never heard one peep out of it. Usually fledglings will vocalize with a begging call to be fed, but it can also get the attention of predators. Perhaps this little fledgling has already had a close call and has decided to sit and wait silently.
