Hi there, it's me, that girl katie, Here are some source tips and pictures too on ideas for having an Owl Birthday Party.
I am not a fan of pinata's but I found one that didn't require hitting it, instead you just pulled a string.
If you make the cupcake/cake, I recommend using mini marshmallows instead of coconut for the Owls belly.
