Climatic conditions represent one of the main constraints that influence avian calling behavior. Here, we monitored the daily calling activity of the Undulated Tinamou (Crypturellus undulatus) and the Chaco Chachalaca (Ortalis canicollis) during the dry and wet seasons in the Brazilian Pantanal. We aimed to assess the effects of climate predictors on the vocal activity of these focal species and evaluate whether these effects may vary among seasons. Air temperature was positively associated with the daily calling activity of both species during the dry season. However, the vocal activity of both species was unrelated to air temperature during the wet season, when higher temperatures occur. Daily rainfall was positively related to the daily calling activity of both species during the dry season, when rainfall events are scarce and seem to act as a trigger for breeding phenology of the focal species. Nonetheless, air temperature was negatively associated with the daily calling activity of the Undulated Tinamou during the wet season, when rainfall was abundant. This study improves our understanding of the vocal behavior of tropical birds and their relationships with climate, but further research is needed to elucidate the mechanisms behind the associations found in our study.

AbstractVervet monkeys in Amboseli National Park, Kenya are preyed upon by four types of predator: mammalian carnivores, eagles, baboons, and snakes. Over a 14 month period, adult males and females gave first alarm calls at comparable rates. Both observation on the frequency of alarm-calling and experiments on the duration of alarm-calling indicated that high-ranking adult males and females gave alarm calls more often than low-ranking adult males and females. Individuals who alarm-called most often did not vocalize most often during social interactions, nor did they spend more time than others surveying the habitat around them. There was some tendency, however, for females who alarm-called most often to precede other females in group progressions. Limited evidence suggests that adult males who gave most alarm calls were more likely than other males to have fathered the group's juveniles and infants. Among adult females, however, there was no correlation between number of offspring and frequency of first alarm calls. Females who gave alarm calls most often were not more likely than other females to spend large proportions of observation time more than 2 m from their offspring. Data on a small sample of confirmed predatory attacks suggest that the offspring of high-ranking females may have been more vulnerable than other immatures to predation. Such differential vulnerability may have resulted in part from the tendency of the offspring of high-ranking females to precede other juveniles in group progressions. Vervets of all age/sex classes alarm-called most at those species of predators to which they themselves seemed to be most vulnerable. Adult vervets gave relatively few alarm calls to predators to which their offspring, but not themselves, were vulnerable, even though such alarm calls would have been of low cost to themselves and of great potential benefit to their offspring. While some aspects of the alarm-calling behavior of vervet monkeys are consistent with the hypothesis that their alarms have evolved to benefit kin, in other respects their alarms appear to have the consequence of benefitting only the alarmists themselves. It is likely that both kin and individual selection, acting on an individual's inclusive fitness, have played a role in the evolution of vervet monkeys' alarm calls.

AbstractWe noticed an uncommon phenomenon of female vocalization in the forest litter frog, Rana curtipes during the breeding season. We digitally recorded the male and female vocalization of the litter frogs in the tropical rain forests of the Western Ghats of South India and analyzed the call characteristics. The female call varied from the male call by being single note in composition. In contrast, the male calls were composed of seven to eight notes and longer in duration. We observed that gravid females, occupying the same location every day, emitted low volume calls when numerous males were found calling at that time. Some females arrived asynchronously and called even in the absence of males possibly to declare their receptive condition. Calling females responded agonistically to receptive conspecifics of the same sex. In addition to declaring receptivity, this calling behavior may be a response to adjacent competing females when the males are few.

Passive Acoustic

In coastal waters, anthropogenic activity and its associated sound have been shown to negatively impact aquatic taxa that rely on sound signaling and reception for navigation, prey location, and intraspecific communication. The oyster toadfish Opsanus tau depends on acoustic communication for reproductive success, as males produce ‘boatwhistle’ calls to attract females to their nesting sites. However, it is unknown if in situ vessel sound impacts intraspecific communication in this species. Passive acoustic monitoring using a 4-hydrophone linear array was conducted in Eel Pond, a small harbor in Woods Hole, MA, USA, to monitor the calling behavior of male toadfish. The number of calls pre- and post-exposure to vessel sound was compared. Individual toadfish were localized, and their approximate sound level exposure was predicted using sound mapping. Following exposure to vessel sound, the number of calls significantly decreased compared to the number of calls pre-exposure, with vessel sound overlapping the frequency range of male toadfish boatwhistles. This study provides support that anthropogenic sound can negatively affect intraspecific communication and suggests that in situ vessel sound has the ability to mask boatwhistles and change the calling behavior of male toadfish. Masking could lead to a reduction in intraspecific communication and lower reproductive efficiency within the Eel Pond toadfish population.
