Copulatory behaviors and body condition predict post-mating female hormone concentrations, fertilization success, and primary sex ratios in Japanese quail.

Environmental cues and social interactions are known to influence reproductive physiology and behavior in vertebrates. In female birds, male courtship displays can result in the growth of ovarian follicles, the production of reproductive hormones, and stimulation of oviduct development, all of which have the potential to influence maternal investment. Male Japanese quail follow a typical sequence of copulatory behaviors during a mating interaction and often force copulations with unreceptive females.

Adequacy of and satisfaction with delivery and use of home-delivered meals.

For home-delivered meals to have a beneficial impact on older persons, it is important that both delivery of services and use by older persons are adequate. From November 2004 to February 2005, we conducted a random-sample telephone survey of 1505 New York City home-delivered meals recipients, asking them about adequacy of and satisfaction with delivery of services and use of meal services. Fourteen percent of recipients relied solely on program food.
