A bird enthusiast, facing a court appearance for alleged harassment, killed himself, an inquest has heard.
Mr Jones had been banned from going near an osprey nest
Marc Llewelyn Jones, 47, a former RSPB warden from Bethesda near Bangor, died after throwing himself from the Menai Bridge.
Mr Jones left a note saying he intended to take his own life and could not face the future but further details were not revealed at the hearing in Caernarfon.
Coroner Dewi Pritchard Jones recorded a verdict of suicide.
The inquest heard Mr Jones's body was discovered in the Menai Straits in June 2005.
When a policeman visited his home in Bethesda he found a letter on the sofa.
In it Mr Jones, who worked as a translator, said he could not face the future and intended to kill himself by throwing himself from the Menai Bridge.
According to the coroner Mr Jones had referred to other matters in his letter, but details were not revealed in the inquest.
Mr Jones was on bail at the time of his death following a court appearance on 1 June 2005 where he had denied a harassment charge.
It was brought after he was abusive towards RSPB staff and a police wildlife sergeant near the site of the rare osprey nest in Glaslyn near Porthmadog.
He had also pleaded not guilty to common assault during the same incident.
As part of his bail conditions he had been banned from going within a mile of the breeding site of two ospreys near Porthmadog or any RSPB site for breeding protected birds.
Mr Jones, a former RSPB warden, had been cleared of deliberately disturbing Wales' only colony of little terns at Prestatyn in 2003.
