Abstract: When a reproductively experienced dove is removed from visual isolation and placed in a breeding cage with an unfamiliar mate and a nest containing eggs, it takes about 5–7 days before it will exhibit incubation behavior. However, similarly experienced doves will exhibit incubation within a few minutes of being placed in a breeding cage if they receive a series of progesterone injections during the last 7 days that they are in isolation (Lehrman, 1958). No other hormone produces such a rapid expression of incubation behavior (Lehrman & Brody, 1961). However, the capacity of progesterone to facilitate incubation requires the joint action of other factors, including other hormones and certain external stimuli. Female doves must have a certain level of circulating estrogen (Cheng, 1979; Cheng & Silver, 1975), and male doves must have appropriate levels of testosterone (Komisaruk, 1967; Stern & Lehrman, 1969). Also, both the mate and the nest with eggs provide stimuli that are required before progesterone will induce incubation (Bruder & Lehrman, 1967; Lehrman, Brody, & Wortis, 1961).
