Abstract
Two study sessions of fieldwork on the Hawaiian island of Kauai were undertaken in 2012 and 2014 on the behavior of the feral chickens on the island. The inquiry was directed to understand the nature of social organization given the animals had no natural predators and were largely ignored by the present population. These observations were compared with those of reported captive Jungle Fowl studies and domesticated fowl. Comparisons with other vertebrate populations with out natural predators are considered. Implications for the self-domestication of Homo sapiens are discussed.
Highlights
One is startled to find the serene blue vistas, wide beaches and deep green tropical terrain of the island of Kauai disturbed by the crowing of roosters
The study of any animal is of interest to widen our understanding of behavior and social complexity and their affects on environment and health
What is of most interest to a study of human evolution is the possibility of studying what is unique in human behavior and especially of an animal that has no natural predators
Summary
One is startled to find the serene blue vistas, wide beaches and deep green tropical terrain of the island of Kauai disturbed by the crowing of roosters. It is of interest to this study that Kruijt [15] raised a number of Jungle Fowl in captivity as a control for his field observations, though his focus was on the ontogeny of behavior in relation to instinct, this check provides a useful background He had obtained his animals from a supplier of birds and. Gering [3], recordings suggest hybrid effects on vocalizations, but their results do not inform us as to timing of calls or associations with humans or other vetebrates Another characteristic of the Kauai chickens that differed from behavior seen in domestic chickens in the mainland (California) was the association of males with small numbers of females, from one to four usually.
