Quelea's are the most abundant wild bird species on the planet, all found in sub-Saharan Africa. There an estimated 1.5 BILLION breeding pairs. During the breeding season these birds flock to areas to nest, commonly numbering in the 10's of thousands and have often been seen in flocks estimated to be over 1 million strong. They can literally blacken the sky in flocks of this size while flying. For farmers it's a serious problem, these birds can wipe out an entire harvest in hours, leaving your years work and economy leveled. The sound of the birds in flight can sound like a gust of wind or even an incoming airplane when the flock is in great number. Truly remarkable and just another thing to love about Africa.
