You can say this word either PILLium or PI-lium.
This is one of those words which make you take notice of something you see many times a day. There are lots of pilea all around you, but mostly unregarded.

A pileum is the bit from the bottom of the beak of a bird to the back part of its head.
Neat, huh? As Edmund tells Catherine in Northanger Abbey: 'You have gained a new source of enjoyment, and it is as well to have as many holds upon happiness as possible.'
So let's all admire the birds!
