The golden eagle has no natural predators, with its main threat coming from humans who poison or shoot it.
- The golden eagle last bred in Wales during the 18th century, after which hunting made it extinct.
- Most of the UK's breeding pairs are in Scotland (more than 400 in 2003), although some have been reintroduced to Ireland in recent years.
- The banning of certain pesticides since the 1960s has helped the population to recover, along with efforts to improve habits for the eagles to live in.
- The birds can have a wingspan of more than 2 metres.
- The golden eagle has a varied diet and will prey on a variety of creatures depending on their habitat. In Scotland, they target hares and grouse, and seabirds in coastal areas.
The Army's latest "spy in the sky" unmanned aircraft, which was tested in Wales, is due to begin flying over British skies this week.
Watchkeeper, a reconnaissance and surveillance unmanned air system (UAS), has a wingspan of 35 feet and can fly at an altitude of up to 16,000 feet.
It has been designed to loiter over areas of interest for "significantly longer" than existing systems, providing clear surveillance pictures to troops on the ground.
Network Rail is planning to re-open one section of the Cambrian Coast railway between Dovey Junction and Barmouth this week. The Cambrian Coast line has been closed following severe storm damage at the start of this year.

Repairs to the Cambrian Coast railway are expected to be completed in mid-May and it is estimated to cost around £10m.
Pembrokeshire County Council says it is helping police with their investigation after ten bus passengers were rescued on Saturday night.
Pembrokeshire County Council’s own enquiries confirmed the road was in the process of being closed and that signage was being erected at Pen-y-Cwm, north of Newgale. However, the Council operatives at Pen-y-Cwm were already directing traffic to use an alternative safe route avoiding the Newgale road. The bus driver was informed of the situation at Newgale and that the alternative route should be followed. However the driver chose to continue his journey along the main road.

A Council operative followed the bus in his own car equipped with a flashing orange beacon on the roof. He was also flashing his headlights in an attempt the stop the bus but was unsuccessful. A member of the public on the bridge at the bottom Pen-y-Cwm Hill also tried to flag the bus down with a torch but he too was unsuccessful. The Council has provided information to the police in relation to their investigation into the incident.
