Little 'ole me, I've lost my tree...

One Lonely Filbert Seedling

There were two baby filbert trees sitting on my porch,
A thief came flying by.
Now there’s one baby filbert tree sitting on my porch,
While I search and I cry and I sigh.

Oh where, oh where has my filbert tree gone?
Oh where, oh where can it be?
It was on my front porch with the other one.
Oh where, oh where can it be?

Little ‘ole me, I’ve lost my tree,
And don’t know where to find it.
I’m left all alone with the one that stayed home,
And I’ve given up hope of finding it.

Seriously - what steals filbert seedlings off of front porches?
Raccoons? Deer? Squirrels? Dogs?
And why take one and leave one behind for Pete's sake?

I'm stumped.
