Why do females sing?—pair communication and other song functions in eastern bluebirds
A clear link between the function of female song in pair communication and the likely selective force of long-term pair bonds acting on eastern bluebird reproductive success is demonstrated.
Song variation between sexes and among subspecies of New Zealand Fantail (Rhipidura fuliginosa)
ABSTRACT Variation in bird song occurs at many levels, including between sexes and among geographic regions. Variation can be due to differences in function, habitat, selection or drift. Quantifying
Female song in eastern bluebirds varies in acoustic structure according to social context
Some of the first evidence that female song structure may be variable between functional contexts and that females may alter their song structure to encode additional information, such as individual identity is presented.
The singing question: re‐conceptualizing birdsong
This framework focuses research specifically on males, particularly during the north temperate breeding season – reflecting and thereby reinforcing this framework and providing recommendations for next steps to build an inclusive information framework.
Migratory return rates and breeding fidelity in Eastern Bluebirds (Sialia sialis)
The data indicate that Eastern Bluebirds have high return and reunion rates, and many of the bluebirds that mated together in previous breeding seasons appear to not only reunite the next year, but they also return to the same territory and nesting cavity.
Form and Function Predict Acoustic Transmission Properties of the Songs of Male and Female Canyon Wrens
To function effectively, animal signals must transmit through the environment to receivers, and signal transmission properties depend on signal form. Here we investigated how the transmission of
Can we disregard the whole model? Omnibus non-inferiority testing for R2 in multi-variable linear regression and η ^ 2 in ANOVA.

Non-inferiority tests for ANOVA and linear regression analyses are introduced, which correspond to the standard widely used F test for η ^ 2 and R2 , respectively.


A female songbird out-sings male conspecifics during simulated territorial intrusions
This is the first songbird study to show a stronger vocal role in territory defence for females than males, and suggests that intrasexual selection may be greater among females than among males.
Losses of female song with changes from tropical to temperate breeding in the New World blackbirds
Recon reconstructing evolutionary changes in female song and breeding latitude in the New World blackbirds (Icteridae), a family with both temperate and tropical representatives, provides strong evidence that members of this group have moved repeatedly from tropical to temperate breeding ranges and that these range shifts were associated with losses of female song more often than expected by chance.
Female Song Occurs in Songbirds with More Elaborate Female Coloration and Reduced Sexual Dichromatism
The results suggest that female plumage and female song likely evolved together under similar selection pressures and that their respective functions are reinforcing.
Female song and aggression show contrasting relationships to reproductive success when habitat quality differs
The results suggest that female–female contest rules and the intensity of competition differ according to resource availability, which may alter how selection acts on female competitive traits.
No Band Color Effects on Male Courtship Rate or Body Mass in the Zebra Finch: Four Experiments and a Meta-Analysis
Four independent failures to replicate the presumed manipulation of male attractiveness in zebra finches by adding red or green color bands are reported, and it is shown that color bands seem to affect neither male courtship rate nor male body mass.
Birdsong Performance and the Evolution of Simple (Rather than Elaborate) Sexual Signals
It is concluded that the evolution of sexual signals can be unpredictable when their physiology affords multiple or, as here, opposing ways of advertising individual quality.
How much variance can be explained by ecologists and evolutionary biologists?
A meta-analysis using data from 43 published meta-analyses in ecology and evolution with 93 estimates of mean effect size using Pearson's r and 136 estimates using Hedges' d or g revealed that the mean amount of variance (r2) explained was 2.51–5.42%.
Female Song in New World Wood-Warblers (Parulidae)
Recent advances have revealed that female birdsong is widespread and multifunctional. Female song was likely ancestral among songbirds and persists in many lineages today. Nevertheless, many species
Use and possible functions of large song repertoires by male Eastern Bluebirds
Male bluebirds sing during interactions with conspecific males, indicating an aggressive or territorial function, to facilitate the transfer of food to incubating or brooding females, nestling, and fledglings, and to warn mates, nestlings, or fledgling about the presence of a potential predator.
Overall, the general organization was similar in both sexes, and some females sang complex song bouts of more than 30 seconds of uninterrupted song, demonstrating that some females produced a more complex song than some males.
