Sacred Ibis, originating from Sub-Saharan Africa and Southern Irak, was known as a breeding bird in the Netherlands between 2001-2009. With almost all birds originating from captivity, while occurrence of French breeding birds was proven by a birds with a colourring. In 2014 a few birds (3-8) remain during the year after re-capturing the main source. In the same period a big part of the French birds was eradicated. Competition for food and scavenging on eggs of colony breeding birds was seen as a risk in the occurrence of Sacred Ibis, but research in France proves that the species has found an ecological niche in its foraging habits. Scavenging of eggs wasn’t proven in Europe.
