Ms O'Grady's body had been taken to Waterford Regional Hospital, where a post-mortem was to take place.
A garda spokesperson added that a file will be prepared for the Coroners Court.
Mr Bird, who was diagnosed with motor neurone disease, was climbing Croagh Patrick with hundreds of supporters to raise funds for the Irish Motor Neurone Disease Association and suicide prevention charity Pieta House.
The climb raised more than €2 million.
