Details of 201/Chirdon’s first two days of migration

201/Chirdon left Kielder Forest on the morning of 1 September. She was roosting in Norfolk by the evening.

373 km of flying

At 08.57 UTC she was over the River Irthing, which is part of the border between Cumbria and Northumberland. She curved round to a more SE course and back into Northumberland to fly over the South Tyne near Haydon Bridge and past Derwent Reservoir on the border with County Durham.

at Derwent Reservoir 09.54-5 UTC

The Reservoir is well watched but there are no reports of a sighting. 201/Chirdon would have been a dot in the sky.

By 10.24 she was c800m above the terrain west of Durham. She travelled on into North Yorkshire, then East Yorkshire.

just west of the North York Moors National Park

In East Yorkshire she passed near Driffield, which has been in the osprey news this week for the rescue from netting of a Scottish juvenile.

from North to East Yorkshire

The rescued osprey was released, and has been seen at Tophill Low Nature Reserve near Hutton Cranswick. 201/Chirdon flew over the reserve, but at 1100-1200m above the terrain, would not have been noticed.

201/Chirdon crossed the Humber estuary and stopped.

no vessels involved

Lincolnshire mudflats

After her rest, 201/Chirdon headed SE through Lincolnshire before flying over The Wash to Norfolk.

cutting the corners

201/Chirdon carried on for another 15 minutes before the first of several pauses before roosting. Most were on electricity poles, including her roost.

201/Chirdon had a lazy start on 2 September, with several pauses before getting underway properly at 08.49.

225 km of travel

She was west of Norwich by 09.15 and reached the coast near Felixstowe by noon.

keeping near land

She was flying high much of the time, eg as she was about to go offshore near Holland-on-Sea (just east of Clacton-on-Sea) she was c1100m above the terrain. She was mostly low over the sea, but gained altitude again when over land near Bradwell-on-Sea.

By 15.30 she reached the Isle of Grain. She stopped on an obelisk just offshore from Allhallows, then perched on more electricity poles, including to roost.

Poles look like dead trees to the ospreys, so seem ideal perches. Modern electricity poles are relatively safe for perching, although power lines are a threat as, very sadly, a Tweed Valley juvenile found a few days ago.

201/Chirdon was near Rye in the last data received yesterday morning. We’ll cover 3 September activity when we have the full day. To end with, and of absolutely no significance, 201/Chirdon crossed 203/Chesters path yesterday morning. It makes a colourful map!

    What a long first haul ! Glad she’s safe . Wish we could discourage them from landing on power lines. Heart in mouth time. So sad to read of Tweed Valley juvenile. . Thank you once again Joanna

    Well – off to a good start isn’t she… From the tracking, is it obvious when ospreys are mobbed Joanna ? Thanks for the update … she’s certainly on a mission …

      Mobbing isn’t obvious – or not to me! She might have been trying to escape gulls etc when she flew high when nearing the Isle of Grain, but she may have been checking out the lie of the land. And sea! She perched just off the Isle, so didn’t seem bothered by other birds then.
