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).
