Sexually selected colour traits of bird plumage are widely studied. Although the plumage is replaced only at one or two yearly moults, plumage colour has long been shown to change between moults. Nevertheless, most studies measure colour weeks to months after the courtship period, typically at nestling rearing, and it is unclear whether these measurements yield relevant data concerning the primary process of sexual selection. Here we analyse repeated spectrometric data taken from male Collared Flycatchers during social courtship and nestling rearing. We show that some spectral traits are not correlated between the two measurements and that within‐individual correlation declines significantly with the likely exposure of the plumage area to damage and soiling. There is an overall decline in spectral trait exaggeration during breeding, but trait decline is not closely related to measurement latency, especially not in the damage‐exposed areas. Finally, sexual selection estimates differ depending on whether they are derived from spectra measured during courtship or during nestling rearing. These results suggest that, contrary to current practice, measurements of plumage reflectance should be made during the primary period of sexual signalling. Spectral trait decline during breeding could also be studied as a possible signal for mates and neighbours.

“…Placement and attributes of nest location can affect, for example, the risk of predation, access to food resources and the microclimate experienced by the developing embryos (Crabtree et al 1989;Barea 2008). Other studies have also shown that breeding success is linked to availability of nesting habitat (Drobney et al 1998;Browne et al 2005) and season (Lepage et al 2000;Herényi et al 2014).…”

Background: Until recently little was known about factors affecting reproductive parameters of the Turtle Dove (Streptopelia turtur) on intensively cultivated farmland in the Mediterranean area. In this study, the reproductive parameters of this game species were evaluated in relation to location, orchard type, laying period and nest position in central Morocco. Methods: A total of 317 nests were found and analyzed across five breeding seasons (2004-2008) in the Haouz and Tadla regions, over two major agro-ecosystems made up of olive and orange orchards. Nest position, laying period, clutch size and the number of chicks hatched and fledged per nest were determined on 120 study plots. I used Generalized Linear Models (GLMs) with a Poisson distribution and a log link function, including the logarithm of the number of eggs in each clutch as an offset to model the number of chicks hatched and fledged per nest. Results: Clutch-size was not affected by location, orchard type, laying period or nest position. The number of chicks hatched per nest differed between orchard types; they were greater in olive orchards (1.33 ± 0.06) than in orange ones (1.03 ± 0.08), whereas the number of chicks fledged per nest consistently differed with laying period and orchard type, which were higher in the early laying period (1.22 ± 0.07) than in the late period (0.93 ± 0.08) and higher in olive orchards (1.22 ± 0.06) than in orange orchards (0.90 ± 0.06). Neither location nor nest position were related to variation in the fledging success of the Turtle Dove. Conclusions: Olive orchards and the early laying period confer better nesting conditions than orange orchards and the late laying period. Although nest position could be different in each orchard type, it did not affect the breeding success of the Turtle Dove, suggesting that factors other than tree characteristics are influential. Further studies are needed to improve our understanding of the effects of anthropogenic disturbance, especially agricultural activities and hunting, on the productivity of Turtle Dove nests.

“…We predict that not only the repertoire size but also the specific distribution of syllables in the acoustic parameter space can signal individual‐specific characteristics and the better‐quality males produce songs where the acoustic diversity is higher (see also the Theoretical part). The objectives of this study were fourfold: (a) describing the methodology for estimating the components of acoustic diversity in the song of the collared flycatcher; (b) characterising the relationships among the diversity indices and the repertoire size as classical diversity estimate; (c) assessing the biological relevance of the derived traits by estimating the between‐individual consistency of acoustic diversity by calculating the repeatabilities on three time‐scales (within a day, between days and years) based on repeated song recordings from the same males and (d) exploring the relationships between the acoustic diversity and certain aspects of male quality (age, condition and arrival date) that were previously suggested to be important in sexual selection (Herényi et al., 2014; Szász et al., 2019) in this species. The workflow of the methods is shown in Figure 3.…”

The study of the diversity of animal signals on within‐ and among‐species levels is the key to uncover mechanisms that shape the evolution of communication systems. However, the methods used to quantify acoustic diversity (like repertoire size) lack to grasp several aspects of acoustic diversity. Here, we propose a new framework for the study of animal communication, in which we decompose the acoustic diversity with the methodological toolbox from community ecology. We explore how different diversity estimates reflecting different aspects of acoustic diversity can be applied to characterise the complexity of acoustic signals. We propose that this approach can be used in a wide range of animal taxa to derive further insights about the function and evolution of communication systems besides the traditional methods. To illustrate the use of our approach in a case study, we used the song of the collared flycatcher Ficedula albicollis as model system. Based on three frequency and time variables, we calculated three functional diversity indices (FRic, FEve and FDiv) to characterise the distribution of song elements (syllables) in the acoustic parameter space. We aimed to uncover the interrelations of diversity indices, reveal the degree of among‐individual consistency and investigate their relationships with certain aspects of individual quality (body condition, age and arrival date). We found that the diversity indices were largely independent of each other and showed different consistency patterns that were time‐scale dependent, indicating different signalling potential of individual‐specific attributes. We also found that FEve strongly related to the age of males. Our case study showed that decomposing the diversity into different components can reveal additional biologically meaningful aspects of birdsong.
