Shackles of hardened soda doom a chick at Lake Magadi, where a colony nested in an unusually alkaline area. Even in lakes with less mineral con tent, such fetters sometimes accumulate. Skirting danger, a gray mass of several thousand young lesser flamingos gives wide berth to a tawny eagle on Lake Natron. The predator waits to pick off any weak or soda-laden chicks that fall behind. Fetters show as white anklets on legs of chicks in foreground. Marabou storks sometimes panic breeding colonies into abandoning eggs. Flamingos select nesting sites in terrain so treacherous that flightless predators cannot reach them.
