Greater Blue-eared Glossy-Starling Debate

We recently spotted a Greater Blue-eared Glossy-Starling Lamprotornis chalybaeus in Madeira Island. There is no information in the customs services of the trade of such species.In Cani??al where the bird has been spotted there is a harbour, but no boat came in the last six months from North Africa, all from Europe.We would like to ear your views if the bird is an escapee or accidental.Are records of this species in Morocco or Mauritania?
