This book was released on 2020-03-31 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: The variety of social systems among the New World blackbirds (Family Icteridae) and the structural simplicity of their foraging environment provide excellent opportunities for testing theorics about the adaptive significance of their behavior. Here Gordon Orians presents the results of his many years of research on how blackbirds utilize their marsh environments during the breeding season. These results stem from information he gathered on three species during ten breeding seasons in the Pacific Northwest, on Red-winged blackbirds during two breeding seasons in Costa Rica, and on three species during one breeding season in Argentina. The author uses models derived from Darwin's theory of natural selection to predict the behavior and morphology of individuals as well as the statistical properties of their populations. First he tests models that predict habitat selection, foraging behavior, territoriality, and mate selection. Then he considers some population patterns, especially range of use of environmental resources and overlap among species, that may result from those individual attributes. Professor Orianns concludes with an overview of the structure of bird communities in marshes of the world and the relation of these patterns to overall source availability in these simple but productive habitats.

Download or read book Nest Survival of Tricolored Blackbirds in California's San Joaquin Valley written by Kelly Weintraub and published by . This book was released on 2013 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Post hoc analyses indicated that larger population sizes had a negative effect on DSR in 2011 but a positive effect in 2012 and that the presence of white-faced ibis (Plegadis chihi) lowered tricolored blackbird nest survival. Number of young produced per nest varied by site, was lowest in colonies of 1,000 - 5,000 birds, and was higher in 2011 than 2012. Managers of habitats used by tricolored blackbirds should continue to protect colonies in silage fields and consider management approaches that increase the height of nesting substrate and discourage white-faced ibis from nesting in association with tricolored blackbirds. In addition, small colonies that begin nesting late in the season can be productive and should not be dismissed as unimportant.
