When Ravana kidnapped Sita, he was obstructed on the way by Jatayu, a large bird. But the powerful Ravana defeated Jatayu in the fight and cut his wing
SB Canto 9
Lord Rāmacandra, whose lotus feet are worshiped by Lord Brahmā and Lord Śiva, had assumed the form of a human being. Thus He performed the funeral ceremony of Jaṭāyu, who was killed by Rāvaṇa. The Lord then killed the demon named Kabandha, and after making friends with the monkey chiefs, killing Vāli and arranging for the deliverance of mother Sītā, He went to the beach of the ocean.
When Rāvaṇa kidnapped Sītā, he was obstructed on the way by Jaṭāyu, a large bird. But the powerful Rāvaṇa defeated Jaṭāyu in the fight and cut his wing. When Rāmacandra was searching for Sītā, He found Jaṭāyu almost dead and was informed that Sītā has been carried off by Rāvaṇa. When Jaṭāyu died, Lord Rāmacandra did the duty of a son by performing the funeral ceremony, and then He made friends with the monkeys to deliver Sītādevī.
