Influence of diet on the gastrointestinal flora of wintering red kites

ResumenDiets primarily based on meat remains found in carcass dumps or wild prey can have different influences on scavengers' health, including the infection with food-borne pathogens, but there is little information on this topic in wild birds. This study provides descriptive data on faecal flora composition of red kites, Milvus milvus, wintering in two areas of central Spain where they typically feed on a mixed diet of wild prey and livestock carrion (Segovia) or primarily on wild prey, especially lagomorphs (Madrid). Despite these different food habits, no clear link between diet and the composition, richness and prevalence of bacterial species of the faecal microbiota of red kites was found. Salmonella sp. was not isolated in samples from Madrid, but was found at medium prevalence in Segovia. This difference was presumably associated with the consumption of livestock carrion, especially of swine and poultry, in carcass dumps where unsatisfactory sanitation can increase the presence of this and other potentially pathogenic bacteria, which need to be further assessed. © 2014 Springer-Verlag Berlin Heidelberg.
