Studies on animal behavior are vital for several reasons most importantly in connection with conservation, livestock and wildlife management, animal welfare, sustainable use of animal and human resources, and ultimately for better understanding of human behavior. In its formative stages, behavioral studies were mostly observational till the classic work of Lorenz, tin Bergen and Frisch catapulted them into Nobel laureates. This had a cascading effect on research on animal behavior resulting in intense studies in several areas of behavior mainly information acquisition neuroethology and transfer communication,ecological aspects habital related, foraging strategies, migration, predator-prey interactions, population ecology etc., socio-biology parent-filial interaction, co-operation & conflict, grouping & dispersion, social organization etc. reproductive strategies, evolutionary aspects kin selection, altruism, life history strategies etc., physiology behavioral endocrinology, rhythms, neurobiology and applied behavior conservation, animal welfare, livestock production, wild life management, man-animal conflict etc.
