Find the hidden owls around the party.
Variety of owls, 3-D or drawings or printouts
Purchase or draw or print out a variety of owls, as large and as small as you like.
Hide them around your party room, then tell your guests to find the owls. Depending on how many owls you have and how well you have hidden them, you might want to set a time limit on how long they can search, or you could keep going until someone has found ALL the owls.
Give a prize for the winner...maybe they could take their pick of all the owls they found?
