A flock of greater flamingos strides along Fisher's Pan in Namibia's Etosha National Park during rainy season. Particular common during the onset of breeding a group of flamingos masses closely together, walking with an erect posture in a synchronized "quick-step", going first one direction and then another. The tail may be wagged during marching. Size of marching groups can range from a few flamingos to many thousands.
