A rare pair of ospreys have laid their first egg in mid-Wales, which conservationists believe is the first such egg in the area for at least 250 years.

It was laid in a nest near Talybont-on-Usk, near Brecon, Powys, and is a sign the “rare species is fighting back”, said conservation group Usk Valley Ospreys.

The species was wiped out in Wales in the 19th century due to persecution and habitat loss, but has been making a comeback in recent years due to conservation efforts.
