 The hen harrier chicks are fitted with radio transmitters |
Three rare birds of prey are leading experts tracking their movements a merry dance after they fled their nest. The hen harriers were raised this year at Geltsdale reserve near Carlisle, and have been fitted with high-visibility tags and miniature radio transmitters.
The male is now at a Humberside nature reserve, while one of the females was on the Tees marshes, but has since gone missing, as has the other female.
Birdwatchers and walkers are asked to report any sightings to RSPB Geltsdale.
Pete Howard, from the RSPB, said: "Thanks to the innovations of high-visibility wing tags and miniature radio transmitters, we can now track birds like hen harriers as never before.
"I've been astounded by their wanderings, and the information about their movements that we are gathering is incredibly valuable.
"However, despite the technology, the harriers are still leading us a merry dance as they leave tantalising clues for us as they travel across the country."
Hen harriers are one of England's rarest birds of prey, and the pair at the Geltsdale reserve have successfully reared five chicks.
