Early maternal deprivation impairs the behavioral development of young individuals. Recently, strong differences between mothered and maternally deprived chicks have been reported concerning their emotionality, sociality, and spatial skills. Here we investigated long-term and cross-generational impacts of maternal deprivation by comparing the characteristics of the non-reproductive and the maternal behavior of 22 mothered and 22 non-mothered adult female Japanese quail (Coturnix c. japonica) and by comparing the behavior of their respective fostered chicks. We reveal that non-brooded mothers were more fearful and less competent in spatial tasks and expressed impaired maternal care, characterized by more aggression towards chicks, higher activity rates, and more abnormal pacing during the first days of the care period. Chicks' behavior was clearly affected by maternal care inducing strong differences in their fearfulness and social motivation. Our results show both long-term and cross-generational impacts of early maternal deprivation in precocial birds. © 2013 Wiley Periodicals, Inc.
