“…In most species males immediately establish a territory; when females arrive they may choose among males or territories. Several studies have demonstrated a positive correlation between male arrival order and mating order (Brooke 1979;Alatalo et al 1984Alatalo et al , 1986Gottlander 1987;Rades-/iter et al 1987), but if males occupy territories in a decreasing order of quality (e.g., food abundance) it is difficult to determine whether females actually choose a male or the resources defended by the male. Male display rate has been shown to correlate with arrival order (Gottlander 1987;Rades/iter et al 1987) and food abundance (Ydenberg 1984;Davies and Lundberg 1984;Tamm 1985;Rades/iter and Jacobsson 1988;Strain and Mumme 1988;Alatalo etal.…”

Females may choose a mate on his own quality or on the quality of his resources, i.e., his territory. We removed willow warbler males and allowed new males to settle, before the arrival of females, in order to test whether the proximate cue for female choice was any male trait or territory characteristics. The experiment indicates that females base their choice on some male trait. No correlation was found between male settlement order and size (tarsus length, wing length), but males arriving early were in better body condition than males arriving late. The most likely male trait for female choice was singing rate, which was a good indicator of male settlement date. The duration of time between mating and egg laying was shorter in early territories, both in the observational and the experimental data. Since male song rate was correlated with territory quality (e.g., food abundance) the ultimate benefit to females choosing males with high song rates could be a high quality territory.

“…Naturalselection advantages m a y be gained by discriminating females. By choosing males that sing longer songs at a faster rate, females m a y be choosing males that hold territories with an a b u n d a n t food supply (Morton 1982;Gottlander 1987;Radesater et al 1987;Alatalo et al 1990). If in the field we find that females choose males with higher song outputs and those males in turn are defending higher quality territories, we would have support for an adaptive function o f mate choice (Trivets 1972;Boake 1986).…”

“…Singing rate has also been correlated with mating success, (Payne and Payne 1977), male parental care (Greig-Smith 1982), and success at attracting a mate (Gottlander 1987;Radesater et al 1987;Alatalo et al 1990). Providing extra food to Ipswich (savannah) sparrows (Passerculus sandwichensis princeps) increased singing rate and decreased foraging rate, suggesting that song output provided reliable information about a male's energetic condition (Reid 1987).…”

Song output and stimulation of the female in white-throated sparrows

We investigated the importance of song length and singing rate in stimulating female white-throated sparrows, Zonotrichia albicollis. In November 1988 ten female and one male white-throated sparrow were captured during the fall migration. To enhance the expression of sexual receptivity, the females were implanted with 17-beta-estradiol silastic pellets. Using the visual stimulus of a non-singing male to further enhance the expression of sexual receptivity in the females, we found that females gave a greater response, in the form of copulation displays, to a five-note versus a two-note version of a typical male white-throated sparrow song. Each version was played back at four songs per minute. In May 1990 birds were captured and treated as before, except that the two-note song was played at ten songs per minute and the five-note song at four songs per minute. Therefore, each female heard twenty notes per minute. In the second experiment, the females did not show a statistical difference in response to the two-and five-note song playbacks. We interpret the results of the second experiment as indicating the song rate as well as song length is important in stimulating female whitethroated sparrows because increasing the rate of the twonote song brought the response up to the level of response we obtained to the five-note song played at the slower rate. We conclude that in white-throated sparrows, song output is important for female stimulation.

“…Male-specific long-range calls made by birds, amphibians and mammals can carry for distances of up to 2.5 km through indigenous environments, and they serve as long-distance advertisements of an animal's presence in a certain location (birds [Radesater et al, 1987;Alatalo et al, 1990]; amphibians [Prestwich, 1994]; mammals [Clutton-Brock and Albon, 1979;McComb, 1991;Delgado, 2006]). In contrast, short-range calls are generally only audible by individuals within the same social group and in close proximity to the caller, e.g.…”

Male-Specific Use of the Purr in the Ring-Tailed Lemur <b><i>(Lemur catta)</i></b>

In mammals, purring has been described in mostly affiliative contexts. In the ring-tailed lemur (Lemur catta), both males and females purr, but only males were observed purring in agonistic contexts. In order to determine whether male ring-tailed lemurs purr as aggressive displays during intrasexual agonistic encounters, 480 h of focal data were collected on 25 adult males from Beza Mahafaly Special Reserve, Madagascar, from March to July 2010. The male purring rate increased during periods of male-male agonism when compared to times without intrasexual agonism, and the purring rate was positively correlated with male dominance rank. However, the purring rate was not significantly higher during winning agonistic interactions when compared with losing encounters. My results indicate that the male ring-tailed lemur purr is used most frequently as an agonistic vocalization in male-male encounters, in addition to being used less frequently in other social contexts, including during tail-waving at females, resting, scent-marking, feeding and copulation. Dominant males have higher purring rates across social situations, suggesting that the purring rate may be driven by intrinsic male qualities rather than functioning as a meaningful signal in each disparate social context. Male purring in intrasexual agonistic encounters can be added to previously described social contexts for ring-tailed lemur purring.
