Ups and downs

The young ospreys on Nests 2 and 4 are having ups and downs jumping about their nests. The weather is good for a couple of days, then wet – as it has been today. On the technical side, after a glimmer of hope that the Nest 1A streaming problem might be fixed earlier in the week, resolution is now unlikely to be for a couple of weeks. The stream from Nest 4 especially is also playing up, with much freezing, so videos from that nest are limited.

Back to the ospreys. On Nest 2, Aln has been making steady progress. Mostly, she is still fed by EB and (rarely) 37. But she is grasping a fish and tearing off chunks when she feels like a top up. On Friday, she competed with EB for possession of a new delivery from 37.

Experience won!

Aln isn’t exercising that often – mostly after a meal, or when she has defecated. But she is improving her coordination and strengthening her muscles each day.

These two clips show Aln has yet to start ‘helicoptering’ ie hovering above the nest. That activity usually leads to fledging a few days later. Press HD for best quality on all videos.

Aln will be 52 days old on Monday. Kielder youngsters often fledge around the 55 day mark, although there is a range.

The Nest 4 duo will reach 52 days next weekend. Their exercise regime is similar to Aln’s. Both the youngsters have primary feathers that are still well sheathed, in particular the one day younger Alwinton.

They aren’t going short of food -this was the 5th fish delivery on camera.

The pair have rarely attempted to feed themselves. Here, Alwinton has a tentative nibble.

As mentioned earlier, the nestcam footage is freezing often. But here is a relatively ‘freeze-free’ clip of the Aydon and Alwinton exercise routine.

You can see Alwinton is more unsteady, despite those sturdy legs!

Both nests have experienced intrusions over recent days. Yesterday, one of the unseen ospreys was UV. EB was keen to escort him away from her nest.

Neither Nest 4 adult flew after UV, but they didn’t look pleased to see him.

UV spent several hours in the Kielder area. He was wide-ranging over the day, as so often, covering 182 km. A normal ‘excursion day’ for him.

Today, the rain has curtailed action on the nests. Two rare examples…

The forecast is better for tomorrow.
