Migrating swallows

Most of our swallows have left by this time of year; Britain’s swallows overwinter South Africa.

Migrating swallows cover 200 miles a day, mainly during daylight, at speeds of 17-22 miles per hour. The maximum flight speed is 35 mph. 

Here is a video that visualises their route.
