the generally greater control of the process of reproduction by females than by males imply …

This book is a comprehensive study of nest-building behavior in birds. A much-needed
synthesis of the previously scattered literature on this central aspect of avian biology, it is …

According to the theory of mate choice based on heterozygosity, mates should choose each
