AbstractFemale song is widespread across bird species yet rarely reported. Here, we report the first observations and description of female song in the Cyprus Wheatear Oenanthe cypriaca and compare it to male song through the breeding season. Twenty-five percent of colour-ringed females were observed singing at least once, predominantly in April, compared to 71% of males that continued singing through the breeding period. We suggest that female song may have multiple functions in this species, but it may be especially important in territorial defence and mate acquisition.

Provisioning of wildlife, such as backyard bird feeding, can alter animal behavior and ecology in diverse ways. For species that are highly dependent on supplemental resources, it is critical to understand how variation in the degree of provisioning, as occurs naturally across backyards, alters wildlife behavior and ecology in ways potentially relevant to disease spread. We experimentally manipulated feeder density at suburban sites and tracked local abundance, foraging behaviors, body mass, and movement in House Finches (Haemorhous mexicanus (P.L. Statius Müller, 1776)), the primary host of a pathogen commonly spread at feeders. Sites with high feeder density harbored higher local House Finch abundance, and birds at these sites had longer feeding bouts and total time on feeders relative to sites with low feeder density. House Finches at high-density feeder sites had lower residual body mass despite greater apparent feeder access. Finally, birds first recorded at low-density feeder sites were more likely to move to neighboring high-density feeder sites than vice versa. Because local abundance and time spent on feeders have both been linked with disease risk in this species, the effects of heterogeneity in bird feeder density on these traits may have important consequences for disease dynamics in this system and more broadly.

Abstract Studies of animal contests have focused on the probability of winning an encounter, because it directly affects the benefits of competition. However, the costs (e.g., physiological stress) and benefits of competition should also depend on the number of aggressive encounters per unit time (combat rate, hereafter) in which the focal individual is involved. Using colourful and drab male house finches (Haemorhous mexicanus) from urban and rural sites, we showed that combat rate was repeatable across the same and different group sizes for birds who won competitions. In addition, colourful urban males exhibited the lowest propensity for frequent aggression (and hence low combat rate). However, male bill size (another trait we previously found to correlate with male competitiveness in this species) was not related to aggressive propensity. Combat rate can be predicted by male identity and some, but not all, predictors of male competitiveness.

General Organization

Abstract While male song and its functions have been well studied, female song has often been overlooked. In this study, we provide a detailed description of the spontaneous female song in a well-studied northern temperate songbird, the European Starling (Sturnus vulgaris). We compared the song organization, complexity, and composition of female and male starlings housed in large outdoor aviaries. Overall, the general organization was similar in both sexes, and some females sang complex song bouts of more than 30 seconds of uninterrupted song. Although some females were capable of singing the four phrase-type categories typically found in male song bouts (whistle, variable, rattle, and high-frequency phrase types), a significantly lower proportion of females sang all four categories of phrase type as compared to males. Our results also revealed large individual variation in song characteristics among females: repertoire size varied between 11 and 36 phrase types, while average song bout length ranged between 10 and 26 seconds. All song parameters (total repertoire size, song bout length, and repertoire size within the four different phrase categories) were significantly lower in females than in males. Nevertheless, except for the number of rattle phrase types, song parameters overlapped between the sexes demonstrating that some females produced a more complex song than some males. Canto de la Hembra en Sturnus vulgaris: Diferencias entre Sexos, Complejidad y Composición Resumen. Mientras que el canto del macho y sus funciones han sido bien estudiados, el canto de las hembras ha sido menos estudiado. En este estudio, brindamos una descripción detallada del canto espontáneo de la hembra en una especie bien estudiada de ave canora del norte templado, Sturnus vulgaris. Comparamos la organización del canto, la complejidad y la composición entre machos y hembras en aviarios de gran tamaño emplazados al aire libre. En total, la organización general fue similar en ambos sexos, y algunas hembras cantaron unidades de canto complejas durante más de 30 segundos de modo ininterrumpido. Aunque algunas hembras fueron capaces de cantar las cuatro categorías de tipos de frases típicamente halladas en las unidades de canto de los machos (silbido, variable, matraqueo y tipos de frases de alta frecuencia), una porción significativamente menor de las hembras cantó todas las cuatro categorías de tipos de frases en comparación con los machos. Nuestros resultados también revelaron gran variación individual entre hembras en las características del canto: el tamaño del repertorio varió entre 11 y 36 tipos de frases, mientras que la duración promedio de la unidad de canto fluctuó entre 10 y 26 segundos. Todos los parámetros examinados del canto (tamaño total del repertorio, duración de la unidad de canto y tamaño del repertorio dentro de las cuatro categorías diferentes de frases) fueron significativamente menores en las hembras que en los machos. A pesar de ello, a excepción del número del tipo de frases de matraqueo, los pará metros del canto se superpusieron entre los sexos, implicando que algunas hembras produjeron un canto más complejo que algunos machos.
