RSPB Scotland has set up a Justgiving web page after being inundated by calls from members of the public asking to contribute to a reward for information about the deaths of 16 birds of prey.
The conservation charity is responding to an outpouring of support from the public, many of whom have expressed a wish to donate money.
Police Scotland confirmed earlier this week that 12 red kites and four buzzards were found dead in Ross-shire. At least some of the birds were illegally poisoned.
RSPB Scotland is offering a £5,000 reward for information that leads to a successful conviction. An anonymous donor has pledged a further £5,000, taking the total on offer to £10,000.
