The first wild beaver to appear in Norfolk in 500 years has wasted little time in making itself at home.

Telltale evidence from trail cameras shows it has been busy felling branches and brusquely warding off inquisitive otters in its new-found riverside territory.

The young Eurasian beaver, whose unexpected arrival at a nature reserve was announced last month, is one of about 3,000 of the species which now populate rivers from Scotland to Kent. It is part of a trend seeing the once-extinct rodents return to Britain in growing numbers.
