After delving into the brain of the zebra finch, researchers revealed how the birds are able to learn the courtship songs sung by their fathers. It turns out they have specialized nerve cells that allow them to memorize one note at a time.
Researchers from the University of Southern Denmark recently discovered that despite having different organs for voice production, humans and birds use the exact same physical mechanism to make vocalizations.
Birds that are able to mate with their "true love" have a higher rate of reproduction success and are more committed to their offspring, according to researchers from the Max Planck Institute for Ornithology.
Finches that experienced stress hormones in food at a young age chose social networks outside of their immediate family, and didn't imitate parents' ways. Will their somewhat random socializing factor into the spread of bird flu?
Many will argue that there is no worse parent than one who abandons their child - especially for selfish reasons. Unfortunately, evolution doesn't select for what we think is "right" but for what works best. Now, new research has found that not only is abandoning a chick to be raised by others beneficial for zebra finches, but it may even be a trait that is selected for - improving the species as a whole.
