By the time the young noddies leave, they carry these hitchhiking seeds away to other islands.
新一代黑燕鸥离巢的时候，会带着这些搭顺风车的种子前往其它岛屿。
But sometimes the pisonia trees are too successful.
但有时腺果藤树的策略过于成功。
If a fledgling, testing out its wings, drops to the ground, it can get covered with the seeds.
如果幼鸟在学习飞翔时跌落地面，它身上会挂满这些种子。
Entangled and weighed down, if it can't free itself,the youngster will starve.

The pisonia may have failed to disperse these seeds, but it will soon have fertiliser for its roots.
