That's the problem with good endings with wildlife. You never really know for sure unless you see the family actually reunite--and that makes it hard.
But chances are this little one's mom came back looking for him and he's back with his family now! So I think that's the end of the tale we should go with!
"We are--each of us--dying; it's how we live in the meantime that makes the difference."
"It's not what you gather, but what you scatter that tells what kind of life you have lived!"
"Be kinder than necessary, for everyone you meet is fighting some kind of battle."
