Good news and bad news…

PX1 has died in Scotland

Jeremy Paxman with PX1

We have great news this week, but also some very sad news about the ospreys of Tweed Valley. The sad news is that we are certain that PX1, best known as Jeremy Paxman’s osprey, is dead. The data received since he was last tracked in the north of Scotland is consistent with a static bird on the ground.

He was doing so well previously, touring and exploring Scotland’s flow country. We are very sad to lose this bird, as he had spent two winters in residence at the gold mines in Sanso, Southern Mali after leaving the Tweed Valley nest site. He returned to Scotland this spring, but unfortunately, it seems he wasn’t destined to make it home.

The tale of his family is a sorry one, as the nest he was raised from stands empty this year. His father drowned on returning to Scotland this spring, while his mother (we think) was driven away from the nest site by the very dominant Mrs O.

PX1’s brother. meanwhile, died 100 miles south of Paris on his first migration trip. The male osprey reared by his parents last year died in Switzerland, and the female was last tracked in Spain. His nearest surviving close relative is FK8, who had the same father, yellow 8C, but a different mother, green DN. Both those adult birds are now dead.

FK8 is nesting

FK8 data reveals clusters of points where she is in one place for long periods of time presumably incubating eggs.

The known surviving family member, FK8, is believed to be nesting this year – the data that her tag is giving us shows that she remains in the same location with just short, brief trips away. This would indicate a bird at a nest site incubating eggs and just taking a few stretches away from the site. We hope that she does well. and can bring some genetic continuity to this branch of our osprey family.

Benefits of long term species monitoring

The revealing tracker data shows very clearly that the need for continued, robust, conservation of these magnificent birds is far from over. The breeding success of more than 200 chicks raised in Tweed Valley lulls us into a false sense of security, giving the impression that the species is beginning to thrive. It is only when we track the birds further and find out the survival rate of dispersing birds that we can see that numbers are not increasing as we would have liked or expected, and that fatalities are high.
The value of monitoring over the long term is vital to identify trends in their population dynamics, and to identify threats to their survival.

Mrs O and SS – Parents at last

vlcsnap-2018-06-12-22h25m30s103 Proudparents of two chicks

Two chicks hatched on 11 June

On to happier news! This week, Mrs O and SS became parents at last! The first chick hatched on 11 June after 39 days of incubation. Later the same morning, egg number two also hatched, after a period of only 35 days of incubation. The warm weather must have played a part in the advancement of the incubation period for the second egg.

Mrs O was very restless prior to hatching, and kept stepping away from the eggs and peering down at them, turning her head backwards and forwards as though listening. She could perhaps hear the tapping inside the eggs, and the cheeping of the little ones as they pecked their way out into the world. Some forage of the new arrivals can be seen below.

We are just waiting for news of the third egg now, and we are beginning to wonder if this will also hatch earlier than expected. Both adult birds are very settled – SS brought in fish for Mrs O and she fed the two little ones. She is currently moulting, and some of her feathers are on the side of the nest. A bold chaffinch hopped onto the nest and took a few of the downy feathers away for his own abode… Recycling at its best, avian style!
