From the plebeian pigeon to the rarest bird of all. The Spix's macaw, or the little blue macaw, may be the most endangered bird in the world. The last remaining member of its species known to be living in the wild, a lone male, was discovered in Brazil in 1990, but it has not been seen since 2000.

Approximately 120 individuals now survive in captive breeding programs. Fifty of these are kept in the Al Wabra Wildlife Preservation in Qatar where Andrew captured them on film.
