Portland Bill in Dorset is an important staging area for migrant birds in spring. The English Channel becomes an ornithological motorway and thousands of migrants, big and small, rare and common, will land here after travelling thousands of miles. Because this rocky coast juts five miles out into the sea it is a magnet for migrant birds. Tired and hungry travellers land here. It's a bit wild and windswept, but it's the first safe landfall that many birds find in the UK. At the southern tip of Portland is a bird observatory where you can see migration happening right before your eyes. A blackthorn bush is one of the few things in flower at the moment. It is producing nectar and attracting insects, and therefore insect-eating birds. There is a willow warbler and a whitethroat there now. Portland is like a south coast cafe for these birds!
