The reason why this one is the right answer is because this one has all the things that are required it to have. Which are the right places and the right amount of commas and also, the punctuation mark in the end. The commas are placed in such a way, where it is perfectly the right feeling that you are saying a sentence that is made without any mistakes. The commas in the middle of the sentence make it more easier to understand the steps in which the baby bird did what it did.
