With the beaks, also, the feathers are neatly combed 

 and smoothed. When they wish to oil their feathers they 

 squeeze a drop of oil out of the oil-can at the root of the 

 tail, and then, passing the feathers through the beak, oil 

 and smooth them. The oil gland is always found in 

 waterfowls, that need to have a water-proof plumage.

Fishing bill of Pelican, showing large pouch.
