Geographic distributions of Gyps and their sampled locations. Darker diagonal lines represent year-round distributions, while thinner lines represent non-breeding distributions. Cross-hatched distributions (e.g. G. f. fulvus in Turkey) represent restricted breeding distributions. Uncertainty in G. fulvus subspecies distributions is represented by a question mark (?) at range overlap (i.e., Afghanistan). Geographic distributions determined using information provided by Mundy et al. , del Hoyo et al. , Ferguson-Lees & Christie , and Rasmussen & Anderton .
