Nest 2 is too interesting!

The last post described another visit to Kielder by UV, who is most attracted to the Nest 2 area. He isn’t the only one. There have been more intrusions recorded by the nestcam on that nest than Nest 1A.

The weather on Saturday was very poor and there were no intrusions. EB brought a fish for the three juveniles, 37 delivered two. EB and Y5 haven’t been since so could have begun their migrations early on Sunday.

When the nestcam started on Sunday Blue CN2 was on the nest – he is a 2013 male from Dumfries and Galloway who has been seen at Kielder previously in 2016.

He was present on and off for at least 2 hours 40 minutes. Here is a video of parts of that visit, plus EB exhibiting similar behaviour a few days earlier.

playCN2 left the nest without persuasion by 37 who delivered a fish for Y4 and Y6 an hour later. The day progressed normally thereafter.

On Monday the nest was empty during a wet morning but both juveniles were around in the afternoon. There was a visit from one from another nest, possibly Y7 from Nest 4.

Yesterday both juveniles were on the nest when streaming began, preening and food soliciting. It wasn’t long before intrusions began, at first by a distant osprey but that soon changed.

Things went downhill for the juveniles from that point.

CN2’s repeated low flights over the nest resulted in Y4 flying off and CN2 making himself at home.

He was on and off most of the rest of the day. Y6 tried to return to the nest but was pushed off by CN2. Here is a video of  the events in the morning.14080983_836373679832111_918645105_n

Today Y6 has been on and off the nest – she was shouting at a bird on her first landing but it was unseen by the nestcam.

CN2 was thought to be male when ringed and physically the thin tarsi and long legs plus lightly speckled shallow chest band support that. But the behaviour is much more like a female.

It is of some concern that 37 hasn’t been seen for over a day however Y6’s crop does not look as empty as CN2’s and 37 could be provisioning Y4 and Y6 elsewhere.

The weather is good for migration so we may not see much more of the remaining members of the Nest 2 family this year. Y4 and Y6 must be looking forward to peace and quiet elsewhere!

    Not a nice experience for Y6 ! Tegid also suffered a hostile attack by Blue 24 at Dyfi. Not nice at all even if it’s natural behavoir. And where was Y6 ‘s dad in all that!!

      As 37 is fine he adopted a low profile! At the end of the season defence is less important than when there are eggs or tiny chicks to protect.

      Seeing intruders divebombing nests is hard to watch, but as you say it is natural behaviour.
