The Role of Body Size, Phylogeny, and Ambient Noise in the Evolution of Bird Song
Morton found that the average emphasized frequency in the songs of tropical bird species in low-forest habitats was lower than that of species in grassland or edge habitats. He suggested that thisExpand

Seasonal plasticity in the adult brain
Seasonal plasticity of structure and function is a fundamental feature of nervous systems in a wide variety of animals that occupy seasonal environments. Excellent examples of seasonal brain changesExpand

Seasonal Changes in Testosterone, Neural Attributes of Song Control Nuclei, and Song Structure in Wild Songbirds
Seasonal changes in the neural attributes of brain nuclei that control song in songbirds are among the most pronounced examples of naturally occurring plasticity in the adult brain of any vertebrate.Expand

Functional aspects of song learning in songbirds.
The oscine passerines, or 'songbirds', are one of the few animal taxa in which individuals learn their vocal signals. Recent comparative studies reveal a remarkable diversity of song-learningExpand

The active space of red-winged blackbird song
SummaryActive space, that distance from the source over which signal amplitude remains above the detection threshold of potential receivers, was determined for Red-winged Blackbird (AgelaiusExpand

Plasticity of the Adult Avian Song Control System
Abstract: There is extensive plasticity of the song behavior of birds and the neuroendocrine circuit that regulates this behavior in adulthood. One of the most pronounced examples of plasticity,Expand

Long-range communication of species identity by song in the Red-winged Blackbird
SummaryAdaptations of Red-winged Blackbird (Agelaius phoeniceus) song for communication of species identity over long distances were studied in an upland pasture in Ithaca, New York. This songExpand

Comparative approaches to the avian song system.
There is extensive diversity among the 4000 species of songbirds in different aspects of song behavior, including the timing of vocal learning, sex patterns of song production, number of songs thatExpand

Song learning in birds: diversity and plasticity, opportunities and challenges
A common trend in neuroscience is convergence on selected model systems. Underlying this approach is an often implicit assumption that mechanisms observed in one species are characteristic of allExpand

Steroid Hormones Act Transsynaptically within the Forebrain to Regulate Neuronal Phenotype and Song Stereotypy
Steroid sex hormones induce dramatic seasonal changes in reproductive related behaviors and their underlying neural substrates in seasonally breeding vertebrates. For example, in adult white-crownedExpand
