“…Monarcha flycatchers are insectivorous leaf gleaners that inhabit the lower and middle strata of forests (Filardi and Smith 2008;Uy et al 2009). They are socially monogamous, and breeding has been recorded throughout the year.…”

“…As an example of incipient speciation on islands, Mayr (1942) discussed several populations of the Monarcha castaneiventris flycatcher endemic to the Solomon Islands that vary in body size and, most distinctly, in plumage color (see also Mayr and Diamond 2001;Filardi and Smith 2005;Uy et al 2009). In particular, two subspecies endemic to islands that are a mere 8 km apart in the southeast region of the archipelago are very similar in morphology but differ strikingly in plumage color.…”

“…1). Phylogenetic analyses of the entire M. castaneiventris complex show that M. c. megarhynchus and M. c. ugiensis form a well-supported clade that is sister to the other M. castaneiventris subspecies; however, the two taxa are not reciprocally monophyletic as a result of the retention of ancestral polymorphisms caused by their recent divergence and/or gene flow (Uy et al 2009;J. Poelstra and J.…”

Little is known, however, about the genetic changes responsible for these differences in mating signals. Populations of the Monarcha castaneiventris flycatcher vary in plumage color across the Solomon Islands, with a subspecies on Makira Island having chestnut bellies and blue-black upper parts (Monarcha castaneiventris megarhynchus) and a subspecies on neighboring satellite islands being entirely blue-black (melanic; Monarcha castaneiventris ugiensis). Here we show that a single nonsynonymous point mutation in the melanocortin-1 receptor (MC1R) gene is present in all melanic birds from one island (Santa Ana) but absent in all chestnut-bellied birds from Makira Island, implicating this mutation in causing melanism. Birds from a second satellite island (Ugi) do not show the same perfect association between this MC1R variant and plumage color, suggesting an alternative mechanism for melanism on this island. Finally, taxidermic mount presentation experiments in Makira (chestnut) and Santa Ana (melanic) suggest that the plumage difference mediates species recognition. Assuming that the signals used in species recognition are also used in mutual mate choice, our results indicate that a single amino acid substitution contributes to speciation.

“…Female responses to male songs are difficult to assess using field experiments, first because recognition may be based on contextual cues such as location, and second because playback treatments typically elicit aggressive responses from resident males (Grant & Grant 2002;Seddon & Tobias 2007;Uy et al 2009). Therefore, we conducted playbacks on captive females in a natural setting.…”

Character displacement from the receiver's perspective: species and mate recognition despite convergent signals in suboscine birds

Many social animals use long-distance signals to attract mates and defend territories. They face the twin challenges of discriminating between species to identify conspecific mates, and between individuals to recognize collaborators and competitors. It is therefore often assumed that long-distance signals are under strong selection for species-specificity and individual distinctiveness, and that this will drive character displacement when closely related species meet, particularly in noisy environments. However, the occurrence of signal stereotypy and convergence in rainforest species seems to contradict these ideas, and raises the question of whether receivers in these systems can recognize species or individuals by long-distance signals alone. Here, we test for acoustically mediated recognition in two sympatric antbird species that are known to have convergent songs. We show that male songs are stereotyped yet individually distinctive, and we use playback experiments to demonstrate that females can discriminate not only between conspecific and heterospecific males, but between mates and strangers. These findings provide clear evidence that stereotypy and convergence in male signals can be accommodated by fine tuning of perceptual abilities in female receivers, suggesting that the evolutionary forces driving divergent character displacement in animal signals are weaker than is typically assumed.

“…Divergence in mating signals between populations is an important evolutionary process that can facilitate the development of behavioral barriers to gene flow (Uy et al 2009, Brumm et al 2010. In birds, vocalizations play a significant role in species and mate recognition as well as in sexual selection (Darwin 1871, Andersson 1994, Catchpole and Slater 2008 and there is evidence that female preference for particular songs can increase genetic differentiation between populations (Baker 1983, Fleischer and Rothstein 1988, Ellers and Slabbekoorn 2003.…”
