Bugün öğrendim ki: Şafakta ilk ötmek, en yüksek rütbeli horoz için ayrılmış bir ayrıcalıktır.

Cock-a-doodle-don't? A new study finds that roosters low in the _pecking order_ of a small group won't sound off until the top ranked male first crows his morning cock-a-doodle-doo's. In the chicken world, the top-ranked bird in a social group gets first dibs — a chance to peck up food and other resources. Lower-ranking birds in this pecking order must wait their turn to eat. A study now finds that they also wait to crow. And they often sound off in order of their _rank_ , from high to low, reports Tsuyoshi Shimmura. He's a biologist at Nagoya University in Japan. ![](https://www.sciencenewsforstudents.org/wp-content/themes/sciencenews-sns- child/client/src/images/[email protected])
