Severn-Trent flyway
The Severn-Trent flyway is a migratory route, or flyway, used by birds crossing Great Britain from the Humber estuary to the Severn estuary or vice versa. It follows the rivers Humber, Trent, Tame and Severn. The last of these is not connected to the other three, and so birds must cross the gap over the West Midlands conurbation, around Birmingham.
It is used by birds migrating locally, within Britain, and by those migrating to or from Northern and Southern Europe.
Among the birds known to use the flyway are sea ducks such as common scoter and vagrants from North America such as lesser scaup, along with European Aythya species.
