Last spring two male birds - 06(00) and 32(05) - disappeared within a few days of each other from the same area in south-west Rutland. Their disappearances were highly suspicious and lead the RSPB to believe they had been illegally killed - most probably shot. Their view was shared by the local police who investigated the matter on their behalf. Then last week, 08(97) also went missing. Although they had not been reporting 08’s progress on the website so far this year - due to the continued threat of egg collecting - he had returned to Rutland on 29th March, a few days after his mate, 5N(04). They began incubating on 15th April and seemed to be progressing well. 08 was catching a good supply of fish and the birds were sharing incubation duties without problems.
Then everything changed. On Thursday 08 was absent from the nest all day, and still hadn’t returned by dark. They began to worry because they knew that 08 regularly fishes in the areas favoured by 06 and 32 before they disappeared last spring. Nothing changed on Friday and it soon became clear that he was not going to return. 08 is fourteen years old, but they had seen nothing in his behaviour to give any cause for concern. As ‘Lady’ at Loch of Lowes has shown, Ospreys can live well into their twenties. The only conclusion that can be drawn from 08’s disappearance is that he has suffered the same fate as 06 and 32. In all likelihood he has been shot according to the RSPB.

Hmmmm, other than not trusting the rspb as far as i could throw them....
If 08(97) is the resident male of a breeding pair, he would have chased off any contenders (i.e. 06(00) and 32(05)) within a few days of his arrival and pairing up with his mate which would explain last years disappearances.
As to his disappearance, as he had established a territory with a female it is unlikely he would move on. He may have died of natural causes (whilst Ospreys can live into their 20's and especially females, males are shorter lived. 14 years is probably a good age for a male osprey as average life expectancy would be 8 years old. Prey and food is abundant in Rutland (manly coarse fish but also trout as well), so they definitely didn't starve.
He could have been chased off due to disturbance (helicopter or similar) or other disturbance (i.e. mobbed by ravens or similar) and may yet come back if still alive.
Unless and until the RSPB turns up some physical proof, take what they say with a very large pinch of salt.
