Nests 2 and 4 intrusions continue. Including by UV

Daily intrusions continue at Nests 2 and 4. Sometimes only a shadow or a distant bird can be seen, but on Nest 2 several ringed ospreys have landed, or come close enough to be identified. All have been to Kielder Forest & Water Park a number of times already.

Blue FR1 had been at Derwent Reservoir the previous day, continuing his roaming activity just like Kielder’s own UV. Talking of him…

UV didn’t go far, spending about an hour perching on various stumps and snags on a clear fell. The adults can’t have been there, although field observations frequently find EB using the area. Comparison of UV and Aln’s data show that Aln was in the same area, between 100 and 800m away from UV over the period. Regular readers may recall that last year UV and Nest 4 juvenile male Y8 perched on the edge of a block of timber very near each other, and moved together. When UV flew from his nearest point to Aln, she didn’t follow him.

Aln has continued exploring Kielder Forest. The furthest point away from her nest was over 18km from home. She still tends to lie in the nest some days, as well as perch in various areas, and normally receives fish from either EB or 37 on the nest.

EB could leave on migration at any time. Last year, she wasn’t seen after 20 August – she was still around this morning. She and 37 are seldom on the nest at the same time, but when they are their behaviour is more like courting ospreys, as is often observed near the end of the season.

Nest 4’s camera has captured only two ringed ospreys recently. Blue  CN2 and UV intruded at different times on 15 August, as already reported on the blog. The juveniles aren’t spending much time on the nest. Aydon tends to take a fish elsewhere –  to dine away from Alwinton’s nagging for a share, perhaps!

Mrs 69 has been bringing fish for the juveniles on most days recently. She has probably caught them herself and, usually, she has eaten the head before arriving. As with the adults on Nest 2, when 69 and Mrs 69 are together, their behaviour is more courtship/bonding mode.  Their way!

During early April, 69 would often hang onto a fish rather than hand it over to the waiting partner. But he has provided well for his family, overall, this season.

This morning, Mrs 69 arrived with a fish but rather than leave it for the juveniles, she fed Aydon.

one of the last feeds by mum?

Not much longer for family photos.
