Eagle expert preys for success in hatching their eggs.
Mr Griffiths, owner of the Welsh Hawking Centre, near Barry, has taken in a pair of golden eagles and a pair of bald eagles in the hope of hatching their eggs.
It is a delicate task, but if it succeeds, each egg could be worth pounds 10,000.
Mr Griffiths said: "A friend brought them in and so I haven't had an opportunity to name them yet.
"They have laid eggs for him but he hasn't been able to hatch them.
"Now, I have got some considerable experience in this area with some expensive incubators and I'm confident I can succeed in hatching them."
If he does succeed, Mr Griffiths and his friend will split the proceeds and the eagles will be on permanent display at the centre.
The golden eagles are 25 years old, while Mr Griffiths estimates the bald eagles are about 10 years old.
Mr Griffiths said: "I'm very pleased we have the birds here, particularly the golden eagles because they are always very popular with the public. We used to have one here but it died a few years ago."
