As the river drops dramatically, tumbling down through Hafren Forest, look for the moody buzzard . Defiantly standing its ground, perched on the branch of an old tree, watching every move the walker makes. It waits until the last second before gracefully flying off across the valley. Birds of prey take their food mainly in flight, killing weak birds, because they make easier targets. Man is a predator of wildlife.
Damage is done with firearms, pesticides, illegal traps, etc.
The grey heron is the largest long-legged British bird. It can be seen feeding at all seasons along the river in Gloucestershire. The Wyre Forest, situated on the borders of Shropshire and Worcestershire, is the best remaining native woodland in this country. The strangest creature on the Severn was the Littleton whale .
