A dozen or so griffon vultures, huge birds with white heads and
tawny wings, were wheeling like hang gliders in the gray sky above the
boulder-strewn scrubland.

It was to protect these magnificent birds and other rare and threatened raptors
like the golden and Bonelli’s eagles that Mr. Mónteiro and his wife, Ana
Berliner, both wildlife biologists, began about 15 years ago to piece together
Faia Brava, or “wild cliff” in Portuguese.
