In the european vultures the sense of smell doesn't seeem to play any role,
as in most bird species; specific references can be found among others in
Fischer (1969), de la Fuente (1970), Perco (1995). The food research is
based on sight: the griffon-vulture (_Gyps fulvus_) is able to identify
objects of 10 cm of diameter from an altitude of 1,000 m (Glutz _et al._,
1971). Important is also observation of others scavengers, like crows,
serving as indicators.
