Vocal display behaviours are common throughout the animal kingdom, play important roles in both courtship and aggression, frequent subjects of behavioural research. Although females many species vocalize, an overwhelming fraction research has focused on male display. We investigated vocal female singing mice ( Scotinomys teguina ), small muroid rodents which sexes produce songs consisting trills rapid, downward frequency sweeps. Previous established that increase song production engage precisely timed counter-singing behaviour response to playback conspecific song. tested whether also increased their rate song, they counter-sing, there sexual dimorphisms effort. Our results demonstrate much like males, effort counter-sing song; however, sing fewer shorter compared males. This study further informs understanding establishes mouse as a valuable model for investigating

As a field, ecology has historically misunderstood or overlooked female organisms, assumed that they are ‘similar enough’ to males. The typical unit of study for research stops at the species level, but can be too coarse and obscure important intraspecific differences. Projecting results studies based on only half population (i.e. males) onto females misleading, if not dangerous, as birds differ from males in key aspects their biology. Birds widespread sexed more often than most other taxa; yet although it uses them model current ornithological is disproportionately male birds. We review some fields pertinent conservation highlight biases gaps. find that, counter ‘traditional’ assumptions, reproductive roles balanced between sexes across many, all, species. In addition, sing, tend dispersive males, have lower survival, use different habitats – which implications may affected by climate change differently. call ornithologists separately because lack attention these differences real‐world implications. Potential solutions include training observers recognize traits, using field methods increase detection (e.g. catching during migration season, DNA determine sex), broadening geographical regions recruiting diverse group scientists help equalize research.

Abstract In this study, we documented for the first time singing on nest (SOTN) in 74% of 65 Northern Mockingbird (Mimus polyglottos) nests that were monitored with continuous-running video cameras (8,353.9 hr sampled). As predicted, higher rates SOTN significantly decreased daily survival nests. occurred almost exclusively by females during egg stage and 86% (48 56) which had sampling from stage. While extensive at population level, average rate per individual was low (5.24 ± 1.24 s hour We found mixed support hypothesis functions territory maintenance. no hypotheses to coordinate parental care, defend nests, or aid vocal learning. Given limited attention has received mostly anecdotal accounts it, our understanding its costs benefits is lacking. conclude while are quite low, may be more widespread populations than previously thought studies specifically designed test regarding potential critically needed.

Context Cultural divergence refers to changes over time in behavioural traits. These cultural could have important implications for conservation planning, and impact the success of efforts such as translocations. Aims Here, we investigate extent, potential impacts, two isolated populations Floreana mockingbird (Mimus trifasciatus) on Galápagos Islands. Methods Using contemporary recordings vocalisations test spatial vocal differentiation between populations. Furthermore, explore drivers change using morphological measurements historical species. Key results We found evidence temporal mockingbird. accurately classified 75% birds correct based multivariate measures audio canonical analysis principal coordinates (CAP). also significant differences morphometrics populations; specifically, beak depth was associated with frequency modulation, an acoustic measure that is significantly different complexity a period 57 years. Conclusions remaining this endangered Factors morphology drift might been influenced vocalisation across Implications highlight importance considering factors when planning reintroductions species where there need minimise risk assortative mating so maximise genetic diversity.
