Justification for EICAT assessment


The African Sacred Ibis has been observed consuming native species from a range of taxonomic groups in France and the USA. There is no evidence that this has caused declines in the populations of native species (Marion and Marion 1994, Kayser et al. 2005, Vaslin 2005, Yesou and Clergeau 2005, Clergeau and Yesou 2006, Marion 2013, Clergeau et al. 2010, Calle and Gawlik 2011).
