“…Secondly, as shown in the Java sparrow (Lonchura oryzivora), in which duet dancing is a key predictor of mating success (Soma & Iwama, 2017), behavioural displays that allow interactive communication between males and females can contribute to pairformation, and possibly pair-bonding as well (cf. Hall, 2004;Hall & Magrath, 2007;Ręk & Magrath, 2016;Takeda & Kutsukake, 2018).…”

Estrildid finches (family: Estrildidae) are characterised by great intraspecific and intersexual variations in sexual traits, which include courtship song, dance and ornamental colourations of plumage. These features are expected to help us answer some questions about the evolution of sexual signals: (1) why multiple ornaments evolve in socially monogamous species; and (2) why, in certain species, males and females share identical sexual traits. To discuss these, first, I briefly review the past phylogenetic comparative studies of Estrildids and show that the three sexual traits evolved independently. Secondly, I focus on one behavioural component of the courtship dance, nesting material holding display, and test the idea that the display evolved as a signal of nest building ability using phylogenetic comparative approaches. The results showed that males exhibited nesting material holding displays in species where males tend to work harder to prepare nests, which indicates that parental cooperation plays a role in the evolution of sexual signals.

“…Robotic applications have already helped to understand multimodal stimulus processing in the context of territory defence or sexual signalling (e.g. in some frog and bird species 6,4,7 ) but could also open a research window into the development of the perception of multimodal signals. Here we outline the progress in designing a robotic bird, looking and singing like a songbird, the zebra finch Taeniopygia guttata.…”

Understanding animal behaviour through psychophysical experimentation is often limited by insufficiently realistic stimulus representation. Important physical dimensions of signals and cues, especially those that are outside the spectrum of human perception, can be difficult to standardize and control separately with currently available recording and displaying techniques (e.g. video displays). Accurate stimulus control is in particular important when studying multimodal signals, as spatial and temporal alignment between stimuli is often crucial. Especially for audiovisual presentations, some of these limitations can be circumvented by the employment of animal robots that are superior to video presentations in all situations requiring realistic 3D presentations to animals. Here we report the development of a robotic zebra finch, called RoboFinch, and how it can be used to study vocal learning in a songbird, the zebra finch.

“…Therefore, here, we sought to examine the functions of both male and female courtship within a social environment. In some socially monogamous avian species, both sexes engage in courtship displays, such as song duetting ( 8 ), and multimodal courtship displays [for example, magpie-larks ( 9 ), albatrosses ( 10 ), cranes ( 11 , 12 ), and grebes ( 13 )]. These types of mutual courtship displays are assumed to play an important role in pair bonding and its maintenance ( 14 , 15 ), and thus have the potential to convey information related to mating status, which could be useful for mating rivals or individuals who seek opportunities for extra-pair mating.…”
