Population trends of the griffon vulture Gyps fulvus in Northern Spain between 1969 and 1989 in relation to conservation measures. Donázar, J. A. & Fernández, C.

Paper doi abstract bibtex In a region of northern Spain the griffon vulture Gyps fulvus population remained stable between 1969 and 1975, hovering around 282 pairs in 23 colonies. In 1979 there were 364 pairs in 26 colonies, in 1984, 589 pairs in 32 colonies, and in 1989, 1097 pairs in 46 colonies. Previously, in the 1950s and 1960s, the population had decreased. The recovery of the species may have been caused by the cessation of human-induced mortality. The creation of feeding stations did not have positive effects because there has always been enough food available to maintain the vulture population.
