When a satellite-tagged hen harrier dies of natural causes, what happens next?
The satellite tag continues to transmit, leading investigators to find the dead bird and determine the cause of death. The tag doesn’t suddenly stop transmitting and the bird’s corpse doesn’t suddenly vanish in to thin air, even several days after death.

One of this year’s young satellite-tagged hen harriers, Hermione, has been found dead on the Isle of Mull. She died of natural causes in late September and her body (and sat tag) has been retrieved, just a few kilometres from where she’d fledged in August. Full story on the RSPB Skydancer blog here.
No driven grouse moors on Mull. No mysterious disappearance of Hermione. No sudden cessation of signals from her satellite tag. No suspicious circumstances. Just a straightforward natural death and a straightforward recovery of her body, aided by the signals from her still-fully-functional satellite tag. Amazing, eh?
