Use of Song Types by Male Carolina Chickadees (Poecile carolinensis)
… especially in Black-capped chickadees. Chickadee song has received much less study, particularly in Carolina chickadees. Carolina chickadee songs vary widely with geography and few detailed accounts their song repertoires are available. Also, the use of song types among breeding stages has not …

Comparative study of the vocalizations and singing behavior of four Aimophila sparrows
… Sparrows were also included. Ten, 5, 3, and 6 types of calls were present in the repertoires of Rufous-crowns, Rufous-wings, Cassin's, and Five-stripes, respectively. Songs were sung from the ground, or from a variety of perch heights. Only Cassin's and Rufous-crowns regularly sang flight …

Behavioural and neural studies of male singing and female phonotaxis behaviour in crickets
… production of calling, courtship, and rivalry songs in male crickets and the recognition of the songs by conspecifics. Male crickets sing by rhythmically opening and closing the forewings to generate sound pulses and song patterns. The central command for singing is controlled by the brain. The …

Song learning in the song sparrow (Melospiza melodia): ecological and social factors
During song learning, songbirds are exposed to many more songs then they keep for their final song repertoire and little is known about how or why a bird selects the particular songs he sings as an adult. These studies examine the social and ecological factors that influence song learning and …

Geographic variation of song within and between subspecies of the Mangrove Warbler (Setophaga petechia castaneiceps and S. p. rhizophorae)
Bird song characteristics are unique for each species, but songs are not identical among con-specific individuals and variations may occur at different geographic scales throughout a species distribution. Geographic song variation is common in many species, particularly in Passerines due to their …

Studies on the neural processing of conspecific songs in the cricket Teleogryllus oceanicus (Le Guillou)
… to the identification of its conspecific songs. T. oceanicus males produce three song types related to three different behavioural strategies. Although each of the three songs have very similar frequency spectra their temporal patterns are very different and highly complex, particularly …

The effect of diet and parasite load on female phonotaxis in the Texas field cricket, Gryllus integer
… to variations in species-specific male calling songs. This selectivity has been shown to be age-dependent; older females are less choosy. However, female quality should also affect female selectivity. The effect of female quality on mate choice was examined in Gryllus integer by comparing the …

Taxonomy, phylogeny and biogeography of cisticolas (Cisticola spp.)
… analyses indicated that frequency components of songs were correlated with habitat type and body size. These correlations, though, disappeared when phylogeny was controlled for indicating that phylogenetic history rather than habitat preference influenced song character distribution. Some song …

Harmony in Discord: An Analysis of Catalan Folk Song
Traditional folk song is a reflection of the society that creates it. In the Catalan case it reflects not only Catalan society but also those of Valencia and the Balearic Islands, for whom forms of the Catalan language are native. This present thesis investigates the corpus of folk song in Catalan …

The role of individual variation in auditory and visual processing: implications for mate choice
… I used a cross-correlation analysis of males’ song-types and found that pairs of songs were more dissimilar if they were directed to receivers that differed in sex compared to songs directed to receivers of the same sex. These data support the Motivational Structural Rules hypothesis because …
