Ospreys at Kielder

Ospreys at Kielder

2021 is the 13th successive year of ospreys breeding in Kielder Forest. By late March several males had returned to claim their nests. Intensive effort has resulted in cameras being installed on 7 nests, wonderful news which should provide the most detailed ever insight into the population.

2020 was the first time 7 nests were occupied, although at Nest 3 the breeding female failed to find a new mate after her partner moved to a new platform with a new female. Particularly exciting was the discovery that 2014 Nest 1 male Blue UV had paired with a Scottish female on Nest 5A. He is the first osprey hatched in the forest to try and breed here. Sadly, despite diligent incubation, their eggs failed to hatch. We hope they both return and have success in 2021.

In 2020 10 young ospreys fledged successfully and migrated in late August, the joint highest number. The breeding season was poor in Scotland and some of northern England, so an additional 10 birds in the population is an important contribution. Perhaps this year a record number of youngsters will leave at the end of the season.

The history of ospreys at Kielder is summarised on the timeline and 2021's key events can be found https://kielderospreys.wpcomstaging.com/timeline-2017/

Ongoing Covid restrictions are being regularly reviewed regards whether there will be any  2021 Osprey Watch events or Calvert Kielder cruises.

Usually, each year once the ospreys return to Kielder, Northumberland Wildlife Trust coordinates a team of knowledgeable volunteers who share their expertise with visitors.  And Calvert Kielder would normally run seasonal Osprey and Wildlife Cruises, providing a great way to have a chance to see the birds up close.

Between late March and early September Ospreys often hunt over the water. The birds use all parts of the reservoir, but some favourite areas are either side of the water at the dam, the area between Bull Crag and Leaplish Bay at Kielder Waterside and at Leaplish Bay itself. The ospreys regularly hunt soon after first light and again in the early evening, around 17.30-18.00, but can be active at any time of the day. As the breeding season goes on, more fish will be required by ever-hungry growing chicks.
