Skimming on the Rufiji River

From the deck of Sand Rivers Selous, watching the African Skimmers fishing is superb entertainment. 

Using their amazing elongated lower mandible, they hunt by feel alone, and can hunt late into the night while their competitors...

...like this Malachite Kingfisher...

...and this African Fish Eagle hunt by day.

It's obvious that skimmers are related to Terns, but they have taken the term adaptation to a whole new level with their crazy bills.
