A download at Nest 3 yesterday coincided with a visit to Kielder by UV. He was near Nest 3 at download time! There was no indication from footage or vocalisation from the incubating male that UV was close by, only the later data revealed his presence. The likely reason there was no chipping or alarming is that the male didn’t see UV because he was facing the wrong way.
More on what else UV did later in this post.
The Nest 3 footage for the last few days suggests a peaceful time, but with only a couple of hours of insight a day firm conclusions can’t be drawn. Both ospreys are often on the nest. An ‘aaah’ image.
Frequently the male is the one incubating when the recordings are made. In the image above he took over once the female, furthest from the camera, left the eggs. In the next one the female eats on the edge.
In another clip we were fortunate to see the female preen out a primary feather from her left wing.
Which one was it? A later clip revealed all.
Back to UV’s flying visit to Kielder yesterday. He arrived near Nest 2, a favourite route. As usual EB was unamused. In the last few seconds UV’s shadow is visible in the bottom quarter of the clip. Press HD for best quality.
UV also passed close to Nest 4 although Mrs 69 did no more than watch him heading away.
Why did UV spend half an hour or so flying around the Forest? He showed no interest in foraging. UV knows ospreys attract ospreys, and that there are four nests in an extended area surrounding the largest man-made reservoir in northern Europe. So we can expect further visits to establish whether there are singletons around.
