Griff, a golden eagle, has gone missing from World of Owls in Randalstown.
Griff accidentally escaped from the sanctuary on Friday afternoon and the volunteers are concerned for his safety.
World Of Owls is Northern Ireland’s premier owl, bird of prey and exotic animal conservation centre and is run by volunteers.
If anyone is visiting the Randalstown area or going for a walk in the forest, please keep your eyes open for Griff.
Searchers have spent the weekend trying to locate Griff and return him to the centre.
If anyone sees him, please contact World of Owls through their Facebook page.
