Like Father Like Son: Cultural and Genetic Contributions to Song Inheritance in an Estrildid Finch by Rebecca N. Lewis, Rebecca N. Lewis, Masayo Soma, Selvino R. de Kort, R. Tucker Gilman

“…These findings suggest that high learning fidelity of song material, i.e., song structure and note characteristics, could allow novel variants to be preserved and accumulate over generations, with implications for evolution and conservation. …”

“…In black-capped chickadees (Poecille atricapillus), habitat quality is known to affect song structure, with birds in high-quality habitat (mature forest) having a higher song consistency than birds in low-quality habitat (young forest). …”

Genetic divergence, population differentiation and phylogeography of the cicada Subpsaltria yangi based on molecular and acoustic data: an example of the early stage of speciation? by Yunxiang Liu, Christopher H. Dietrich, Cong Wei

“…This population is also significantly different in calling song structure from other populations. Conclusions Geographical barriers (i.e., the deserts and semi-deserts surrounding the Helan Mountains), possibly coupled with related ecological differences, may have driven population divergence and allopatric speciation. …”

Can a bird brain do phonology? by Bridget D. Samuels, Bridget D. Samuels

“…Analyses of vocal learning, song structure, and the distribution of song elements have similarly revealed a remarkable number of shared characteristics with human speech. …”

Verbal art as heuristic for semantic analyses by Matt Coler, Patrice Guyot, Edwin Banegas-Flores

“…We provide a musical and linguistic analysis of the non-prosodic poetic song structure. We detail the octosyllabic, homeoteleutonic strategies for line formation, the melodic and rhythmic characteristics, and outline the syntactic, morphological, and semantic strategies used in forming semantic couplets. …”

More Rhythmic Interactions in Two (or Three) Aksak Performances by Fernando Benadon

“…Goldberg (this issue) presents evidence of interactions between percussive timing and song structure in two 3+2+2-meter Balkan performances. …”

Imagining the un-encoded: staging affect in Blondel de Nesle’s Mes cuers me fait conmencier by Leach, EE

“…In an article published in Music Analysis I argued that the finely wrought complexities of melody in trouvère song have been obscured by the persistent treatment of song structure as merely reflecting that of the poetry, its phrases bounded by the poetic line. …”

Sexual selection and ecological generalism are correlated in antbirds. by Tobias, J, Seddon, N

“…Using phylogenetic comparative methods, we test this prediction by exploring relationships between traits assumed to be sexually selected (plumage dichromatism and song structure) and traits assumed to be naturally selected (altitudinal range and habitat range) in a diverse family of tropical birds. …”

Ecological drivers of song evolution in birds: Disentangling the effects of habitat and morphology by Derryberry, EP, Seddon, N, Derryberry, GE, Claramunt, S, Seeholzer, GF, Brumfield, RT, Tobias, N

“…In comparison, direct ecological selection has weaker and more limited effects on song structure. Our results illustrate the importance of considering multiple deterministic processes in the evolution of mating signals.…”

Sex role similarity and sexual selection predict male and female song elaboration and dimorphism in fairy‐wrens by Karan J. Odom, Kristal E. Cain, Michelle L. Hall, Naomi E. Langmore, Raoul A. Mulder, Sonia Kleindorfer, Jordan Karubian, Lyanne Brouwer, Erik D. Enbody, John Anthony Jones, Jenélle L. Dowling, Ana V. Leitão, Emma I. Greig, Christine Evans, Allison E. Johnson, Kimberley K.‐A. Meyers, Marcelo Araya‐Salas, Michael S. Webster

“…At the same time, selection pressures associated with sex role similarity appear to favor sex role similarity in song structure.…”

Humpback whale song and foraging behavior on an antarctic feeding ground. by Alison K Stimpert, Lindsey E Peavey, Ari S Friedlaender, Douglas P Nowacek

“…Reports of humpback whale (Megaptera novaeangliae) song chorusing occurring outside the breeding grounds are becoming more common, but song structure and underwater behavior of individual singers on feeding grounds and migration routes remain unknown. …”

Physically challenging song traits, male quality, and reproductive success in house wrens. by Emily R A Cramer

“…I tested whether vocal deviation and trill consistency are signals of male quality in house wrens (Troglodytes aedon), a species with complex song structure. Males' singing ability did not correlate with male quality, except that older males sang with higher trill consistency, and males with more consistent trills responded more aggressively to playback (although a previous study found no effect of stimulus trill consistency on males' responses to playback). …”

Correlated evolution of beak morphology and song in the neotropical woodcreeper radiation. by Derryberry, E, Seddon, N, Claramunt, S, Tobias, J, Baker, A, Aleixo, A, Brumfield, RT

“…This bounded phenotypic space for song structure supports the hypothesis that passerine birds face a motor constraint during song production. …”

Absence of population structure across elevational gradients despite large phenotypic variation in mountain chickadees (Poecile gambeli) by Carrie L. Branch, Joshua P. Jahner, Dovid Y. Kozlovsky, Thomas L. Parchman, Vladimir V. Pravosudov

“…Food-caching mountain chickadees inhabit a continuous elevation gradient in the Sierra Nevada, and birds living at harsher, high elevations have better spatial memory ability and exhibit differences in male song structure and female mate preference compared to birds inhabiting milder, low elevations. …”

Evolutionary relationships of courtship songs in the parasitic wasp genus, Cotesia (Hymenoptera: Braconidae). by Justin P Bredlau, Karen M Kester

“…Principal component analysis converted the seven elements characterized into four uncorrelated components used in a hierarchical cluster analysis and grouped species by similarity of song structure. Species songs varied significantly in duration of repeating pulse and buzz elements and/or in fundamental frequency. …”

Range-wide spatial mapping reveals convergent character displacement of bird song by Seddon, N, Tobias, J, Kirschel, A

“…By modelling the variation in song structure of two ecologically similar species of Hypocnemis antbird across western Amazonia, we show that their territorial signals converge such that trait similarity peaks in the sympatric zone, where intense interspecific territoriality between these taxa has previously been demonstrated. …”

Natural Patterns in the Dawn and Dusk Choruses of a Neotropical Songbird in Relation to an Urban Sound Environment by Noelia Bustamante, Álvaro Garitano-Zavala

“…Although changes in the timing of the daily organization of acoustic communication have been previously reported, there is a significant gap regarding possible variations in song structure between dawn and dusk choruses. Considering that urbanization imposes different soundscapes for dawn and dusk choruses, we postulate two hypotheses: (i) there are variations in song parameters between dawn and dusk choruses, and (ii) such parameters within the city will vary in response to urban noise. …”

Singer identification model using data augmentation and enhanced feature conversion with hybrid feature vector and machine learning by Serhat Hizlisoy, Recep Sinan Arslan, Emel Çolakoğlu

“…As a result of the tests and systematic evaluations, it has been shown that a certain level of success has been achieved in the determination of the singer who sings the song, and that the song is in a stable structure against the changes in the singing style and song structure. The results were analyzed in a database of 9 singers and 180 songs. …”
