A group of cyclists had a close encounter with the bird on a Carmarthenshire hillside. It is believed to have escaped from captivity.
The RSPB's Big Schools' Birdwatch forms part of this year's Big Garden Birdwatch - the world's biggest wildlife survey.
As the RSPB's birdwatch survey gets underway, here's a guide to how you can spot some of the most common garden birds.
A wildlife observatory has officially opened today at the Cors Dyfi Nature Reserve in Powys.
It will offer visitors a 360-degree panoramic view of the Dyfi Valley.
The observatory, which is part of the Dyfi Osprey Project, already attracts 40,000 visitors a year and there are hopes the new facility will boost numbers further.
A brand new observatory opening today on Cors Dyfi, home of the Dyfi Osprey Project, has been called a 'world class facility.'
Visitors will get a 360 degree panoramic view of the Dyfi Valley, allowing them to experience the ecosystem from a totally new perspective.
– Emyr Evans, 360 Project Manager
We now have a world class facility that will enable us to connect people with wildlife like never before in Wales. It takes forward our vision of enhancing people's relationship with nature and learning about the natural world around us.
The 360 Observatory takes wildlife watching and learning to a higher level, quite literally.
A brand new 360 observatory is opening later today on the Cors Dyfi reserve, home of the Dyfi Osprey Project.
It will provide a full 360 degree panoramic view of the Dyfi Valley with the Pumlumon Mountains and Snowdonia National Park.
The £1.4 million project was funded by the Heritage Lottery Fund, Communities and Nature, and Montgomeryshire Wildlife Trust.
It has also been supported by thousands of volunteer hours and has created four jobs for the Dyfi Valley.
The Dyfi Osprey Project, only open in the summer months, brings in 40,000 visitors a year, and up to £350,000 to the local economy.
The new Observatory will be open for 12 months a year and it is hoped will bring added visitors and value to the area.
Police in Mid and West Wales have warned the public not to approach a massive golden eagle that has been spotted in the hills of Carmarthenshire.
It's thought the bird - which can have a wingspan of six feet - has escaped from captivity.
Alexandra Lodge reports from Llanllwni mountain
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.
Children across Wales have been learning how to tell their sparrows from their starlings today as part of the RSPB's biggest wildlife survey.
It marks the start of the charity's Big Schools' Birdwatch, which records the types of birds found in and around school grounds.
Sarah Powell went along to a school in the Vale of Glamorgan to see if she could spot any!
"Seeing it first hand is the single best way to enthuse young people about nature, and by watching birds from their classroom window, they can learn so much" says Tim Wort from RSPB Cymru.
"It's fun, easy and simple to set up, it works for all ages, and even if it's a dull, rainy January day you can still gaze out of the classroom and see a flash of colour."
