“…The negative loading of range of precipitation is also an indication of less limiting conditions because in our database, environments with larger ranges of variation in precipitation were also the wettest and presumably less limiting habitats (Pearson's correlation between mean annual precipitation and range of variation in precipitation, r = 0.836, df = 27, p < 0.001). To summarize, the independent variables considered in the models presented below were CV of precipitation, predictability of temperature, climatic composite, and two additional variables of known importance for the evolution of bird song, namely habitat (open versus forested) [25] and migratory behavior (none, facultative migrant, or obligate migrant) [26, 27]. Information on habitat and migration was obtained from [28].…”

Climatic Patterns Predict the Elaboration of Song Displays in Mockingbirds

Summary Climatic variability and unpredictability [1] affect the distribution and abundance of resources and the timing and duration of breeding opportunities. In vertebrates, climatic variability selects for enhanced cognition when organisms compensate for environmental changes through learning and innovation [2–5]. This hypothesis is supported by larger brain sizes [6], higher foraging innovation rates [7–9], higher reproductive flexibility [10–12], and higher sociality [13] in species living in more variable climates. Male songbirds sing to attract females and repel rivals [14]. Given the reliance of these displays on learning and innovation, we hypothesized that they could also be affected by climatic patterns. Here we show that in the mockingbird family (Aves: Mimidae), species subject to more variable and unpredictable climates have more elaborate song displays. We discuss two potential mechanisms for this result, both of which acknowledge that the complexity of song displays is largely driven by sexual selection [15, 16]. First, stronger selection in more variable and unpredictable climates could lead to the elaboration of signals of quality [14, 17–20]. Alternatively, selection for enhanced learning and innovation in more variable and unpredictable climates might lead to the evolution of signals of intelligence in the context of mate attraction [14, 21–23].

“…Some animals acquire their communication systems partially by learning, including humans, Belding's ground squirrels [36,38], dolphins [51], and many songbirds [30,32]. Although learning is an important feature of many systems, adding this complexity to CoopEvol's orgs would only have served to complicate the results.…”

Cooperative Strategies and the Evolution of Communication

Using communication is not the only cooperative strategy that can evolve when organisms need to solve a problem together. This article describes a model that extends MacLennan and Burghardt's [37] synthetic ethology simulation to show that using a spatial world in a simulation allows a wider range of strategies to evolve in response to environmental demands. The model specifically explores the interaction between population density and resource abundance and their effect on the kinds of cooperative strategies that evolve. Signaling strategies evolve except when population density is high or resource abundance is low.

Vocal matching: the what, the why and the how

Over the years, vocal matching has progressed beyond being an interesting behavioural phenomenon to one that now has relevance to a wide range of fields. In this review, we use birds and cetaceans to explain what vocal matching is, why animals vocally match and how vocal matching can be identified. We show that while the functional aspects of vocal matching are similar, the contexts in which matching is used can differ between taxa. Whereas vocal matching in songbirds facilitates mate attraction and the immediate defence of resources, in parrots and cetaceans it plays a role in the maintenance of social bonds and the promotion of behavioural synchrony. We propose criteria for defining vocal matching with the aim of stimulating more matching studies across a wider range of taxa, including those using other, non-vocal, communication modalities. Finally, we encourage future studies to explore the importance of vocal learning in the development of vocal matching, and the information it may provide to third parties in the communication network.
