Data for: Male-specific nocturnal song functions similar to day song in a diurnal bird species
<p class="MsoNormal">Historically, birdsong research has been biased towards song of male birds at dawn and during the day, even though some diurnal birds sing at night. To address this gap, we studied how song in the willie wagtail, <em>Rhipidura leucophrys</em>—a diurnal species with prolific male-specific nocturnal song during the breeding season—varies with time of day, breeding status, and simulated intrusions. <span>We recorded male nocturnal and dawn song over three breeding seasons and examined how this related to fertile and non-fertile breeding stages of females. To test whether song functions for territory defence, we simulated territorial intrusion experimentally in both sexes with daytime and nighttime playback of male and female song. To test whether nocturnal song could function for mate guarding or post-pairing mate attraction, we describe the mating system of willie wagtails using molecular genetic methods. We showed that both nocturnal and daytime song of male willie wagtails has roles in mate attraction and territory defence, while daytime song by females functioned primarily for territorial defence. </span>Males increased song behaviour during fertile periods of resident females, suggesting possible roles in mate stimulation and mate guarding. <span>Males and females responded similarly to simulated daytime intrusions and no differences were seen in male responses dependent on the time of day.</span> We found 10%-14% of offspring were fathered by extra-pair males, suggesting song may also function for mate guarding and post-pairing mate attraction<span>.</span><span> In a species with small repertoires and simple songs like the willie wagtail, differences between males in overall song output achieved through nocturnal singing may be important in mate attraction and territory defence.</span></p>

FIGURE 8 in Similar look but different song: a new Cicadetta species in the montana complex (Insecta, Hemiptera, Cicadidae)
FIGURE 8. Distribution maps of Cicadetta species in France including Corsica (inset). Internal borders follow administrative divisions ("départements"). Cicadetta cf. montana refer to specimens of the complex that could not be determined at species level because of unavailable acoustic information.

FIGURE 7 A–C. Frequency pattern of a typical long echeme produced by C. cerdaniensis. A, Oscillogram; B, Spectrogram (time vs frequency vs amplitude, colour amplitude scale given on the right) and mean spectrum (frequency vs amplitude) of the first and second parts of the echeme. C, Dominant frequency variation along the echeme. Parameters as in figure 6.
FIGURE 6 A–E in Similar look but different song: a new Cicadetta species in the montana complex (Insecta, Hemiptera, Cicadidae)
FIGURE 6 A–E. Temporal pattern of C. cerdaniensis calling song. A, Oscillogram (time vs amplitude) of two typical sequences, each made of three phrases (P1, P2, P3). Letters refer to temporal zooms depicted in C, D and E; B, Variations of temporal parameters along the phrases. ED, EID, FPD and SPD covary. C, Oscillogram of a typical echeme produced during phrase 1 (P1); D, Oscillogram of a typical echeme produced during phrase 2 (P2); E, Oscillogram of a typical echeme produced during phrase 3 (P3). Abbreviations as in figure 2.

FIGURE 3. Temporal and frequency characteristics of C. cantilatrix sp. nov. calling song. Density distributions were estimated using Gaussian kernel smoothing and plotted over histograms.
FIGURE 4 A–C in Similar look but different song: a new Cicadetta species in the montana complex (Insecta, Hemiptera, Cicadidae)
FIGURE 4 A–C. Frequency pattern of a typical long echeme produced by C. cantilatrix sp. nov. A, Oscillogram; B, Spectrogram (time vs frequency vs amplitude, colour amplitude scale given on the right) and mean spectrum (frequency vs amplitude) of the first and second parts of the echeme; C, Dominant frequency variation along the echeme. Frequency analysis parameters: Hamming window, overlap = 87.5%, frequency resolution = 43 Hz. Short echeme showed similar frequency parameters.
FIGURE 2A–D in Similar look but different song: a new Cicadetta species in the montana complex (Insecta, Hemiptera, Cicadidae)
FIGURE 2A–D. Temporal pattern of C. cantilatrix sp. nov. calling song. A, Oscillogram (time vs amplitude) of two typical sequences, each made of two phrases (P1, P2) with short and long echemes respectively, letters refer to time windows depicted in C and D; B, Variations of temporal parameters along sequences. When ED increases IED decreases and vice versa. FPD covaries with ED while SPD remains constant. Longer IED values separate successive sequences; C, Oscillogram of a typical short echeme produced during phrase 1 (P1); D, Oscillogram of a typical long echeme produced during phrase 2 (P2). ED = echeme duration, IED = inter-echeme duration, FPD = first echeme part duration, SPD = second echeme part duration.
