Aspects of Thyroid Histology in Black-billed Magpies
INVESTIGATIONS of seasonal changes in thyroid histology in wild birds have shown that increases in activity occur in the period preceding and during the annual molt (Davis and Davis, 1954; Assenmacher, 1958; Voitkevich, 1966) and in response to low temperature (Wilson and Farner, 1960; Kendeigh and Wallin, 1966). Involvement of th'e avian thyroid in migration and reproduction has also been sugg...
متن کاملA single ancient origin of brood parasitism in African finches: implications for host-parasite coevolution.
Robust phylogenies for brood-parasitic birds, their hosts, and nearest nesting relatives provide the framework to address historical questions about host-parasite coevolution and the origins of parasitic behavior. We tested phylogenetic hypotheses for the two genera of African brood-parasitic finches, Anomalospiza and Vidua, using mitochondrial DNA sequence data from 43 passeriform species. Our...
متن کاملReassortant H9N2 Influenza Viruses Containing H5N1-Like PB1 Genes Isolated from Black-Billed Magpies in Southern China
H9N2 influenza A viruses have become endemic in different types of terrestrial poultry and wild birds in Asia, and are occasionally transmitted to humans and pigs. To evaluate the role of black-billed magpies (Pica pica) in the evolution of influenza A virus, we conducted two epidemic surveys on avian influenza viruses in wild black-billed magpies in Guangxi, China in 2005 and characterized thr...
