We arrived at the Kidepo River at about noon. Wandered around a bit, ate our lunch. At one-o-clock we encountered a pair of monkeys jumping about in the riverside trees.
Dr Mark Antos, our primate specialist, was most excited. It was imperative that we get good notes and if possible good photographs. These objectives did not align with the monkeys. One fled. The other one, a male, presented itself in harsh light and always partially obscured. I selected this photo from 27 equally bad alternatives because it is possible to see the tail tip, the back of the left hand and the scrotum.
The tail tip is light grey as is the back of the hand. The scrotum is an adorable shade of blue. This distinguishes this Tantalus Monkey from the more common and widespread Vervet. It also narrows the field to the Sudanese subspecies Chlorocebus tantalus marrensis.
One-o-clock Jump was created by Count Basie and other members of his band in 1937 and they used it to close their performances for the next fifty years. Its first performance was on radio. The name was conferred in a hurry because the radio announcer though the original title unsuitable for the delicate ears of the American public. Legend has it that Basie looked up at the studio clock and said the first thing that came to mind. Until then the band had called it Blue Balls.
