By now, most of the adult swallows (now called barn swallows) have headed south on their way to southern Africa for the winter months, returning to our shores in April. At this time there are still a few young swallows around. Only yesterday I spotted several overhead. The latest swallows I have ever seen was a small flock at Bolt Head , Devon on November 7th. I think these were unusually late leaving. Just perhaps they stayed for the winter as in that part of the UK the weather is just about mild enough to provide enough insects.
The long north-south migration of birds beggars belief, especially when young birds make this journey for the first time not having ever done it before. How they travel over 6000 miles there, and then back again, often to the very same nest, is just incredible. A lot must go on inside that pea sized brain.
