Identify the error in the sentence: "Landing on my outstretched hand, I kept perfectly still as Joey's pet parakeet tentatively moved its wings back and forth before quickly flying away."

The phrase "Landing on my outstretched hand" serves as a dangling modifier. A dangling modifier occurs when the introductory phrase does not clearly relate to the subject that follows. In this case, it initially seems to suggest that the speaker is the one landing on their outstretched hand, which is not plausible. The introduction of Joey’s pet parakeet later in the sentence clarifies that it is actually the parakeet landing.

To correct this, the sentence could be rewritten to make clear that it is the parakeet doing the landing, for example: "As Joey's pet parakeet landed on my outstretched hand, I kept perfectly still..." This way, the modifier correctly relates to the subject—Joey’s parakeet.

The other phrases in the sentence do not present grammatical errors and contribute appropriately to the meaning of the sentence.
