Illustration Friday: Nest

For this week's topic, I figured I should look up what does a squirrel nest look like. Well, it turns out it varies. Some look like some bird nests, made of twigs, branches, and leaves. Others are padded holes in the tree. Again, just like some birds'. So the obvious conclusion would be that squirrels are a type of bird :)

In fact, I made up a little silly poem in this spirit:
A silly bird is the squirrel
Its song sounds just like a twirl
It builds nests in the trees
And enjoys mac 'n cheese
And it holds its tail in a curl
