Nancy and her friends find a mystery that''s truly for the birds!

Summer is off to a fun start!

Nancy, Bess, and George have joined Park Pals, a cool program where they get to learn about nature -- stuff like trees, birds, even bugs. Their first stop is an aviary, a place filled with lots of birds, including Carmen, a beautiful hyacinth macaw from South America.

But when Todd Steckler holds a creepy jar of beetles in Bess''s face, she screams -- and Carmen flies the coop! Now the girls have to find Carmen before she''s bird-napped. If they track down the bird, they''ll be made Junior Park Rangers, but if they don''t, they''ll be three very unhappy campers!
