VIDEO: Ospreys Aila and Louis return to their Loch Arkaig nest

The early return of two ospreys to their nest in Lochaber has delighted bird watchers around the world.

Louis and Aila arrived back at their summer home at the weekend and are busy bonding again.

Since returning to the Highlands after wintering in Kenya, the ospreys have been carrying out some necessary repairs and improvements by padding out the nest with sticks and moss.

Fans of the birds have been keeping a close eye on their activities by watching them on a live webcam installed at the Loch Arkaig site last year.

The camera stream was watched by more than 200,000 last summer with footage of the pair beamed all over the world.

People from as far afield as Canada and Australia fell in love with their personalities.

George Anderson, of Woodland Trust Scotland, said: “Louis was a bit of a teenager, Aila would want a fish and he would bring her a stick.

“He is still showing signs of just being a wee bit rubbish but that is what people loved, seeing how they interact with their different personalities – it is like watching a soap on TV.”

Mr Anderson said there were high hopes that Louis and Aila would enjoy another year of success as parents.

But they could face challenges from other birds over the mating season.

He said: “Other ospreys may challenge for the nest or try to take over one of the pair.

“Louis will be bringing sticks in, and fish, partly a display to show that he is the breadwinner for when there are eggs and chicks.

“Hopefully they might raise more and then we could see two or three chicks.”

The birds have returned to Scotland much earlier than expected with Aila arriving almost three weeks earlier than last year.

She laid three eggs over the summer and the pair successfully raised a chick named Lachlan.

Mr Anderson added: “We are looking forward to spending another glorious summer watching an osprey family grow.”

Last year the Woodland Trust and the Arkaig Community Forest partnered up to buy Loch Arkaig Pine Forest.

Since then charity workers have built two new osprey platforms.

Ospreys were persecuted into extinction in the UK during the 19th century, with the birds commonly shot for taxidermy and numbers further reducing due to egg collectors.

Scandinavian ospreys resettled in the UK, primarily Scotland, in the 1950s.
