The horizontal pores on the bark, enable the tree to breathe.

The flowers of a hazel are called catkins.  

Catkins appear before the leaves so they can be pollinated by the wind. If the leaves were on the tree first, the pollen might stick to them.  Hazels have male and female catkins on the same tree.

Male catkins begin to develop in autumn.  They are long and  brownish/yellow in colour.  Early the following spring they become a creamy/yellow colour. 

Female catkins are small and brown with bright red styles.  They ripen after the male catkins.
