Dominions Day!

[Kristoffer O]

The White Stork! Wisest of birds. If you don't count the owl, wisest of birds and animals.

Or, if you don't believe in identified flying objects, the Ostrich perhaps. A more down to earth approach. They are fast anyway. Ostrich express delivery service.

Also Meese have been known to carry small screaming bundles through the dense forests of the cold north. These bundles have never been found in densely populated areas, so there is no evidence that they really contain babies.
