In males of several songbird species, the morphology of forebrain nuclei that control song changes seasonally. The only seasonally breeding songbird in which seasonal changes in the structure of song control nuclei have been reported not to occur is the nonmigratory Nuttall's subspecies of white-crowned sparrow. In the present study, we manipulated(More)
The founding premise of the Ornithological Council is that the ability to make sound policy and management decisions regarding birds and their habitat is dependent on the application of impartial scientific data and the continued collection of such data. The Council works to support this important mission. It serves as a conduit between ornithological(More)
Seasonal plasticity in the morphology of telencephalic nuclei that control song behavior has been reported for diverse species of songbirds. The only published report of a lack of seasonal changes in the song nuclei of a seasonally breeding bird is that of Baker et al. in the Nuttall's subspecies of white-crowned sparrow (Zonotrichia leucophrys nuttalli).(More)
Zebra Finches are the epitome of desert-adapted avian species; i.e. they are able to survive without drinking water for over a year. Whereas transepidermal water loss (TEWL) in naked Zebra Finch nestlings is lower than in adults, and desert adaptation is accompanied by intercellular deposition of epidermal multigranular body (MGB) contents, MGB secretion is(More)
The ultrastructure of naked neck epidermis from the ostrich (Struthio camelus) and ventral apterium from watered, and water-deprived, Zebra finches (Taeniopygia [Poephila] guttata castanotis) is presented. The form and distribution of the fully differentiated products of the lipid-enriched multigranular bodies are compared in biopsies post-fixed with osmium(More)
The sounds and songs of birds have inspired the musical compositions of numerous cultures throughout the globe. This article examines a variety of compositions from Western music that feature birdsong and explores the concept of birds as both vocalists and instrumentalists. The concept of birds as composers is then developed-how they use rhythmic(More)
