...Thomas W. Small; Eliot A. Brenowitz; Winfried Wojtenek; Ignacio T. Moore In mid- to high-latitude songbirds, seasonal reproduction is stimulated by increasing day length accompanied by elevated plasma sex steroid levels, increased singing, and growth of the song control nuclei (SCN). Plasticity...

... of forebrain aromatase in oscines is unknown, however, estrogen-sensitive elements of the telencephalic song circuit (an oscine characteristic) may be influenced by local aromatization. Very few studies have investigated the neuroendocrine characteristics of sub-oscine passerines. Species of this passerine sub...
