It would have been easy to overlook that they had ever been in Selborne. 人们很容易忽略掉这些燕子,不曾留意它们在赛耳彭生活过。
And yet the swallows had been in Selborne since the end of February, the martins since the early weeks of April. 但是,雨燕从2月末开始就入住赛耳彭,紫崖燕也在4月的最初几周开始生活于此。
And now they were leaving Selborne on their immense journey back to the equatorial regions of Africa in which they wintered. 现在,它们要离开赛耳彭,开始长途跋涉,回归非洲赤道附近的区域过冬。
