Les chants des oiseaux des villes, le cerveau des colibris et le virus H5N1

We present you there three results of birding researches :
– by studying the songs of a bird species that has succeeded in adapting to urban life, researchers have gained insight into the kinds of environmental pressures that influence where particular songbirds thrive, and the specific attributes of city birds that allow them to adjust to noisy urban environments. The findings, reported by Hans Slabbekoorn and Ardie den Boer-Visser of Leiden University, appeared in the December 5th issue of Current Biology.
– University of Alberta researchers have pinpointed a section in the tiny hummingbird’s brain that may be responsible for its unique ability to stay stationary mid-air and hover.
– University of Georgia researchers have found that the common wood duck and laughing gull are very susceptible to highly pathogenic H5N1 avian influenza viruses and have the potential to transmit them.
