Wonderful woodland wildlife From ospreys to otters, red squirrels to fallow deer, a walk through an English forest will take you into a magical animal kingdom Tweet At the turn of the millennium, ospreys began nesting in England for the first time in 150 years. In 2009 they returned to Kielder Forest, which now has two breeding pairs.

These migratory birds like woods and heathland, mainly in the south, although Sherwood Forest has proved another good spot of late.

The Forestry Commission created viewing areas after otter pawprints were spotted near Fiddlers Ferry, Merseyside.

Spot them in early spring when they first emerge from hibernation.
