©Reginald A.Bourlay DISTURBED IN THEIR MARSHLAND HAUNTS, NOISY LECHWI SPLASH AND BOUND ACROSS ASHALLOW STREAM Soaring over the Kafue flats of Northern Rhodesia, the aviator-photographer came upon this herd of antelopeswhich are closely related tothe waterbucks. When alarmed, they sound forth in a perfect chorus of loud grunts before taking to flight. Their spread hoofs come down with resounding smacks inthe mud and they leave large tracks. "I consider this to be one of my best photographs," Mr. Bourlay writes.
