Nest 4: successful fledging, news from elsewhere and a video

A field visit to Nest 4 yesterday confirmed that Y7, the younger juvenile, had fledged successfully. He was on his parents’ favourite perch initially then flew around the area for several minutes before going back to the nest. He had landed on the nest perch shortly before this record shot of the family.

Later in the day a data download from Y8’s tracker revealed he had fledged sometime prior to 05.17 UTC, when a fix showed him on a perch his parents used last year although they haven’t been seen on it in 2016. Later in the morning he was on the currently very popular tree stump!

So all eleven hatchlings from the four nests have fledged, but Y0 from Nest 1A has not been seen since her fledge and is very unlikely to have survived. The remaining ten young ospreys are thriving with plentiful supplies of fish.

The news from elsewhere… Recently Bird Guides has reported a number of sightings from Derwent Reservoir where 2011 Nest 1 male Blue 39 (also known as Bracken) spent time in 2014 and 2015. He had been caught on the Nest 2 nestcam at Kielder in early April but we haven’t seen him here since.

Last Sunday Tim Robinson was birdwatching at Derwent Reservoir. He saw an osprey catch a fish quite close to him then eat it on a nearby perch. Through his scope Tim could see the Blue Darvic ring clearly. The number was 39. Tim saw another (unringed) osprey  so possibly a partnership is forming – Bird Guides has other reports of two. One describes a juvenile with an adult but as Blue 39/Bracken ate his fish by the water it doesn’t seem likely that he is provisioning a family. Many thanks to Tim for contacting us with his sighting.

The video… On Thursday Nest 1A juveniles were subject to several intrusions over the day. Three were by the same unringed osprey. This video shows the first two landings. Y2, the younger male, was sitting on the camera initially and flew after the intruder before a hasty return home! To even try and chase an intruder away is unusual behaviour by a juvenile but Y2 has mettle. He is also the one who is most active in persuading the intruder to leave.

    So Nest 4 will be using the family group pic for their Christmas card this year then ……. What a feisty little osprey is Y2 ……. any ideas as to the identity of the unringed female? What a pity Y0 wasn’t tagged ……..
