observed that animals perceive only limited portions of their total environment. He asked the reader to consider a tick perched on a blade of grass, being bombarded at any given moment by thousands of wavelengths of both light and sound, hundreds of thousands of odorant molecules, myriad tactile stimuli, and information regarding gravity, humidity, and ambient temperature.

New behaviors that arise, or normal behaviors that vanish from the ethogram, usually signal that something is wrong with the living conditions we have made available to the animal. The third contribution I shall briefly describe from classical ethology is a systematic comparison of the behavior of wild and captive savannah baboons performed by Thelma Rowell (1967)

For example, in our free-living spotted hyena subjects in Kenya, we have gathered preliminary behavioral data indicating that although the hyenas are not terribly bothered by the intramuscular injection involved in being hit by a dart during routine immobilizations, they find the experience of anesthesia itself to be utterly terrifying. In addition, plasma glucocorticoid levels of hyenas that took only a few minutes longer than average to become unconscious were several times as high as in hyenas for which time to unconsciousness was in the normal range (8-13 minutes)

Similarly, spotted hyenas occur in virtually all habitat types in subSaharan Africa, including the arid sands of the Kalahari Desert, the watery world of the Okavango Delta, the dense forests of central and western Africa, and the prey-rich short-grass plains of the Serengeti ecosystem. How then would one describe the environmental conditions confronted in nature by the "average" spotted hyena?
