Abstract

Investigated the intricate relations between prelaying nest-building activity and preovulatory hormonal changes, and the effects of these events on breeding success. 40 pairs of ring doves were allowed to go through a complete breeding cycle under 4 conditions of nest-building opportunity. Nests were self-made, pre-made, pre-made and covered, or removed daily to generate various levels of building activity. Behavioral and hormonal changes were observed throughout the cycle. Blood levels of gonadotropins were monitored by daily measurements with the method of radioimmunoassay. A depression of follicle-stimulating hormone (FSH) typically was associated with every preovulatory surge of luteinizing hormone (LH); an LH surge not accomplished by a FSH dip was not followed by ovulation. Moreover, the FSH depression was significantly correlated with the level of nest-building activity. It is proposed that nest-building activity stimulated preovulatory FSH change and, hence, ovulation. The constructed nest, in turn, appeared to promote incubation behavior. (54 ref)
