Many animals produce vocal sequences that appear complex. Most researchers assume these are well characterized as Markov chains (i.e. the probability of a particular element can be calculated from history only finite number preceding elements). However, this assumption has never been explicitly tested. Furthermore, it is unclear how language could evolve in single step Markovian origin, frequently assumed, no intermediate forms have found between animal communication and human language....
One hypothesis to explain variation in vocal communication animal species is that the complexity of social group influences group's complexity. This social-complexity for also central recent arguments regarding origins human language, but experimental tests are lacking. study investigated whether size, a fundamental component complexity, call functioning organization Carolina chickadees, Poecile carolinensis. In unmanipulated field settings, calls individuals larger groups had greater (more...
Abstract The energetic definition of fitness predicts that natural selection will maximize the residual energy available for growth and reproduction suggesting metabolism might be a target selection. In this experimental study, we investigated whether female male yellow mealworm beetles, T enebrio molitor L . ( C oleoptera: enebrionidae), differ in their hiding behaviour, individual response latency time, duration immobility to treatments mimicking an approaching predation threat. We...
Abstract For decades, texts on methods in animal behavior research have stressed the need for observers of to work minimize potential unconscious biases their coding data. Two major ways minimizing these are carry out data blind key comparisons being made study and high inter‐observer reliability. Over 10 years ago, Burghardt et al. (2012, Ethology , 118, 511) reviewed five journals field coded randomly selected articles from decadal volumes (1970 2010). That earlier article found poor rates...
The "chick-a-dee" call of many Paridae species (titmice, tits, and chickadees) is structurally complex functions in social cohesion. Studies with different Parid suggest that variation the note composition calls relates to a wide variety contexts. An earlier study Carolina chickadees (Poecile carolinensis), focal present study, found receivers responded differently playback differing feeding Here, we addressed whether signalers actually produce contexts those might serve recruitment...
One aim of this study was to apply information theoretical analyses understanding the structural complexity chick-a-dee calls Carolina chickadees, Poecile carolinensis. A second compare that black-capped P. atricapillus, described in an earlier published report (Hailman, Ficken, & 1985). Chick-a-dee were recorded from chickadees a naturalistic observation eastern Tennessee. Calls analyzed using approaches theory, including transition probability matrices, Zipf's rules, entropies, and coding...
In a longitudinal study, the authors housed wild-caught juvenile male cowbirds (Molothrus ater artemisiae) with female or canaries (Serinus canaria) from August until May. The males were then exposed to 3 social contexts. Males directed more vocalizations than cowbirds. vocalized most other males. data revealed plasticity at rudimentary level of reproductive behavior, selective responding members one's own species. Song potency, as assayed by playback, did not predict vocal use. To test...
Reciprocity is fundamental to cooperative behaviour and has been verified in theoretical models. However, there still limited experimental evidence for reciprocity non-primate species. Our results more decisively clarify that with a tit-for-tat enforcement strategy can occur among breeding pied flycatchers Ficedula hypoleuca separate from considerations of byproduct mutualism. Breeding pairs living close proximity (20–24 m) did exhibit mutualism always assisted mobbing regardless their...
Acoustic signalling is a key mode of communication owing to its instantaneousness and rapid turnover, saliency flexibility ability function strategically in both short- long-range contexts. closely intertwined with collective behaviour social network structure, as it can facilitate the coordination decisions behaviour, play an important role establishing, maintaining modifying relationships. These research topics have each been studied separately represent three well-established areas. Yet,...
