The courtship rituals continue for one to two weeks. During this time, no matter whether a large crowd of birds gathers to size each other up, or there is only one marriage partner in prospect, the male birds always pull out all the stops to show the females what they are made of, performing all kinds of aerial stunts to prove their flying prowess.
求偶儀式持續約一、二個禮拜，此時，不論是成群聚集、互相評頭論足，或鳥單勢孤、僅有一個求偶對象，公鳥都會使出渾身解數，向母鳥展示自己的男性氣魄，大秀飛行技巧，展開各種空中花式表演。
