A third osprey egg has been laid at Loch of the Lowes Wildlife Reserve in Perthshire.

This marks female osprey LF15's 12th egg laid at the Scottish Wildlife Trust reserve since 2015.

The first egg was laid on Saturday and the second was laid before midnight on Monday.

Perthshire ranger, Rachael Hunter, said there is a very small chance of a fourth egg, but that it would be very unusual.

Ospreys were extinct in Britain for much of the 20th century, but they began to recover in the 1960s and around 260 pairs of ospreys now breed in the UK each summer.

"We're delighted that our female has laid three eggs for the fourth time," Ms Hunter said.

"She's been diligently sitting on the eggs except when she swaps incubation duty with her mate while feeding.

"During the next few weeks it's especially important to protect the nest from human disturbance."

The three chicks are expected to hatch in the second half of May.
