What is a Merlin?

Merlin (male) A merlin, as depicted in our Merlin Open Systems logo (see our home page), is a bird of prey. In fact, the merlin is the smallest bird of prey in the United Kingdom. It is a threatened species having suffered a decline of population in recent years, though in some areas they have done well recently.

Merlin (female) Merlin feed on a range of small birds by flying at high speed very close to the ground, and make full use of their acrobatic agility to keep to the contours of the land. They nest in open hilly, mountain or moorland regions in an old stick nest in a tree, or on a cliff face, or in deep beds of heather such as the heather moorlands of the Peak District in England.
