On Thursday 18 May the Kielder Ornithologist, Martin, showed Emyr and Janine of Dyfi Osprey Project Yellow 37 and White YA’s nest areas. (Congratulations to Dyfi on their first hatch today!) Some readers may not know that Emyr and Janine worked at Glaslyn when both males hatched. Now they would see those ospreys with eggs of their own.
An intruder appeared to be around 37’s nest, Nest 2, when we were watching the nestcam at Kielder Castle so we headed there first in case it was still around. What a good decision that turned out to be!
On arrival at a vantage point a buzzard was flying well short of the nest area. But perhaps it was the bird that had disturbed EB’s peace a little earlier? Then Martin spotted a Common Crane far behind the buzzard, heading west towards the Solway Firth.
There are only a couple of records of Common Cranes in Northumberland each year so an exciting start.
The next few minutes were underwhelming – EB was brooding and there was no sign of 37. Then an osprey flew into view, 37 perhaps. But as it came nearer a tracker was visible – could it be UV?
Later, data confirmed it was indeed UV. A thrill! Then two other ospreys arrived on the scene. One was Scottish with a Blue Darvic ring on the left leg.
Janine noticed one of the ospreys had landed in the old nest lower down the fell. It was UV – he’d sat there for about 5 minutes earlier this year. This time he observed proceedings for around 10 minutes.
Then he took off and flew towards the Scottish male.
Another osprey entered the scene at speed from the left. 37 was back to restore order! UV made a discreet exit.
Many thanks to Emyr for sharing his photographs.
The interaction and behaviour of the ospreys was fascinating. Surely the nestcam would have captured some distant ospreys flying around the fells. In fact, during the period three intruding ospreys were mostly over the land behind and right of the nest, none were caught on camera. EB was watching the Scottish and unringed ospreys, but not UV. He was sitting almost directly behind the nestcam. Press HD for best quality on all videos.
Just after we’d left one of the ospreys eventually showed on footage.
UV’s data revealed he returned to Nest 2 later in the afternoon. His shadow can be seen crossing from right to left in this video from 12.11.07.
A memorable day for us all.
