University of Illinois Professor David Clayton and his colleagues said they determined when a zebra finch hears a new song from a member of its own species, the experience affects thousand of genes, offering a new picture of memory in the songbird brain. Clayton said the finding was a surprise since he hadn't expected to see so many genes...

These birds are characterized by the mandibles crossing at their tips, which gives the group its English name. These birds are specialist feeders with a diet of conifer cones, and the unusual bill shape is an adaptation to assist the extraction of the seeds from the cone. They are typically found in higher northern hemisphere latitudes, where their food...
