Waking to the dawn chorus was an especial joy as night faded and the sky grew light heralding a brand new day.

当夜色褪去，醒来就听到清晨鸟语是一件特别快乐的事。 天空放亮，预示着崭新的一天开始了。

The work indicates that humans are subject to the same evolutionary trends that give relatively large eyes to birds that sing first during the dawn chorus or species such as owls that forage at night.

这说明，和这个在黎明鸣叫最早的鸟类或其他诸如猫头鹰等在夜间捕食的物种的大眼眶一样，人类也遵循同样的进化趋势。
