Songs of male yellow warblers (Dendroica petechia), ranging from 1 to 6 years of age, were recorded in the spring and summer of 1984. Recorded repertoire size and number of songs shared with neighbours varied positively with age in the spring but not in summer. Neither clutch initiation date nor fledging success varied with age or number of songs shared but both measures of reproductive success varied with size of recorded song repertoire.

Abstract Evidence from two Cistothorus wrens (C. palustris, C. platensis) has suggested that repertoire size increases with population density and that song imitators are more likely to be site faithful than are song improvisers. We tested these two ideas on a third species, C. meridae, an endemic to the Venezuelan Andes. Of the three Cistothorus wrens, song repertoire sizes of male Mérida Wrens are the smallest, ranging from 18 to 27 song types per male; Mérida Wrens are also most likely to repeat each type several times before switching to a new type. Density of Mérida Wrens was also lowest, from 0.4 to 2.0 territories per 10 ha. These wrens are highly site faithful, with marked microgeographic song variation. Female Mérida Wrens also sing. Overall, data from the Mérida Wren support the ideas that, among Cistothorus wrens, song repertoire sizes increase with population density and site faithfulness promotes song imitation. Variación en el Canto en Cistothorus, con Énfasis en C. meridae Resumen. La evidencia proveniente de dos especies del género Cistothorus (C. palustris, C. platensis) sugiere que el tamaño del repertorio aumenta con la densidad poblacional y que los imitadores de cantos tienen una mayor probabilidad de ser territoriales que los que improvisan. Estas dos ideas fueron probadas en una tercera especie endémica de los Andes venezolanos, C. meridae. El tamaño del repertorio del canto de esta especie, con 18 a 27 tipos de canto por macho, es el más pequeño de estas tres especies. C. meridae también tiene una mayor probabilidad de repetir cada tipo de canto varias veces antes de cambiar a un tipo nuevo. La densidad de C. meridae también fue la menor, con 0.4 a 2.0 territorios por cada 10 hectáreas. C. meridae es muy territorial, con una marcada variación microgeográfica en las cantos. Las hembras de esta especie también cantan. En resumen, estos datos apoyan las ideas de que en el género Cistothorus, el tamaño del repertorio del canto aumenta con la densidad poblacional y que la territorialidad promueve la imitación de cantos.

Older males tend to have a competitive advantage over younger males in sexual selection. Therefore, it is expected that signals used in sexual selection change with age. Although song repertoire size in songbirds is often mentioned as an age-related trait, many species, including the banded wren ( Thryothorus pleurostictus ), do not increase their repertoires after the first year. Here, we show that banded wrens reproduce the trill notes in their songs with less variability between them (i.e. more consistently) when they grow older. In a playback experiment, we also show that banded wrens discriminate between younger and older birds based on structural aspects of their song. In a second experiment, banded wrens also respond differentially to natural songs versus songs with artificially enhanced consistency. We argue that consistency in trill note reproduction may be achieved through practice. Sexual selection in the form of male–male competition may therefore operate on a phenotypic trait, the expression of which is enhanced by practice.

The relationship between song repertoire size and measures of male quality and reproductive success was examined in a Manitoba population of western meadowlarks (Sturnella neglecta). Repertoire size correlated positively with the singer's wing length but not with mass or territory size. Males with larger repertoires tended to pair earlier and males with higher pairing success had larger repertoires. Repertoire size correlated positively with fledging success independently of pairing success. As suggested for other species, repertoire size might serve as a signal to females of male quality. We suggest mechanisms by which this signalling system is maintained.
