Emerging Infectious Diseases • www.cdc.gov/eid • Vol. 20, No. 6, June 2014 1089 viruses showed high nucleotide identities, which suggested that the outbreak viruses in domestic ducks and Baikal teals might have an identical origin. Although research on the epidemiologic features of this outbreak is currently underway, it seems likely that on the basis of reassortant sequence features of the 8 g...

Different vegetation types are distributed in mountains according to altitude, topography and soil. The composition and structure of bird communities in these areas can change in relation to the vegetation gradient, with particular communities occupying each habitat type. In this study we present the changes in composition, species richness and bird abundance over the gradient of forests, savan...

Wild bird watching has become a popular leisure activity in recent years. Very often, people can see birds or hear their sounds, but have no idea what kind of bird species they are seeing. To help people learn to identify bird species from their sounds, we apply speech recognition techniques to build an automatic bird sound identification system. In this system, two acoustic cues are used for a...

The Indonesian pastime of keeping wild birds as pets is threatening the long-term survival of many songbird species on the islands of Java and Bali. Here we present the results of a large-scale household survey of bird-keeping in the six largest cites of Java and Bali that investigates: (1) the scale and conservation significance of bird-keeping and (2) the relative merits of regulatory versus ...

Epiphytes are a common component of neotropical forests, but their importance to birds at the community level and their role in contributing to tropical bird diversity has only rarely been considered. Literature accounts from 55 studies document 193 species of neotropical birds that take nectar, fruits, invertebrates, water, and nesting materials from epiphytes. To quantify the amounts and type...

The study was conducted on 118 partridges (Alectoris graeca) chicks in order to find the effect of non-genetic factors and genetic evaluation live weight carcass this bird. results showed a highly significant superiority weights males over females most age stages (437.71 ± 4.40 vs 375.90 3.66 g/ bird at marketing age) daily gain (ADG) from one day (4.70 0.06 4.01 0.04 day/bird). breeding values...
