    $\begingroup$ Could it be a feather? What made you think it's an animal? $\endgroup$ – Oosaka Apr 24 '17 at 18:08

    $\begingroup$ Can you see any features that appear animal in nature? Eg. Head, eyes, antennae, mouthparts. Could you describe them if yes? $\endgroup$ – hamilthj Apr 24 '17 at 18:20

It is a specialized feather called "down" (like in down pillows, etc.)

Down feathers have a rachis that is shorter than their longest barb. They are completely plumulaceous and have a fluffy appearance, which results from filamentous, noninterlocking barbules.

Many predators, particularly hawks and other birds of prey, will typically pull these whimsical down feathers off of their prey before eating.
