Our most diminutive falcon, the merlin is a pretty bird of prey. It chases small birds, flying low to the ground or hovering in the breeze because of its small size. Resident merlins are joined in winter by Icelandic migrants.

About

The merlin is a small falcon, not much bigger than a blackbird. Merlins feed on small birds, especially meadow pipits which they chase in flight, low to the ground. Their small size also allows them to 'hang' in the breeze as they pursue their prey. They nest on the ground, among the heather. In the winter, our merlin population increases as breeding birds are joined by migrants from Iceland in search of warmer climes.

What to look for

Male merlins are blue-grey above, with a grey head and orangey-cream underparts that are streaked in black. Females are mainly grey-brown, with dark streaking underneath. Merlins have blunt tails and compact, broad-based wings that are pointed at the tip.

Where to find

Nests on moorlands in North and South West England, Wales and Scotland; winters on coastal marshes and farmland in the lowlands.
