Whilst it is a good sign that single ospreys are sufficiently attracted by Kielder Water & Forest Park to want to settle, the resident pairs and their offspring wouldn’t agree when too much attention is focused on their nests.
Nests 2 and 4 have been subject to repeated intrusions over the past few days. The adults on Nest 4 are usually quick to fly to the nest to mantle and dissuade intruders from landing. But Aln appears to have been fighting a solo battle on Nest 2. A parent may have been flying on some occasions.
On Nest 4, the longest intrusion lasted over 4o minutes, with an unringed osprey seen close to the nest at times. This was on Monday.
That was during the long intrusion. Earlier, 69 had a close encounter with, probably, the same bird. Press HD for best quality on all clips.
Possibly the same unringed intruder moved on to Nest 2 in the afternoon. This clip shows the arrival of an unwanted visitor and Aln’s stout defence.
The same osprey was on and off the nest until about 16.00, with Aln the sole defender. She managed to eat in between times!
At 16.37 CN2 landed, followed by the unringed osprey.
Matters became almost farcical a little later, when EB landed with a fish for Aln and the unringed osprey saw an opportunity for a free meal.
In the evening all seemed peaceful.
A different intruder had landed on Nest 2 on Monday.
Blue FF1, a 2014 Perthshire osprey, has been present at times since the end of April. This morning several intruders have been on and off Nest 2, including FF1 and CN2. Plus Aln at times.
