Swallow chicks in the roof of our stable in Norfolk. Awaiting the arrival of the next morsel from their super-busy parents. These little citizens are 4 days old.

Not the best technically as I was balanced on a beam six feet up amongst spiders webs and dust but I hope it captures the essence of these amazing creatures.

The fledglings grow at an amazing rate and fly within 7-8 days of hatching. It's an amazing experience to watch them flourish from helpless little mites into chicks and then see their first, tentative test flights followed shortly by ever braver aerobatics.

Even more astonishing is the fact that they migrate to east Africa to escape the UK winter. They fly up to 250 miles per day to reach their destination and then come all the way back in May.
