Hi

Both are okay, but they mean slightly different things: 1. "I enjoy birds at the park." This means you enjoy seeing or being around birds in general. 2. "I enjoy birds’ singing at the park." This specifically means you enjoy the sound of the birds singing. The second option is more specific and natural if you’re focusing on the birds' songs.

Both sentences can be correct, but they have slightly different meanings: "I enjoy birds at the park." This means you enjoy the presence of birds in the park, possibly watching or observing them. "I enjoy birds’ singing at the park." This is more specific, indicating that you enjoy the sound of birds singing at the park. Choose based on what you want to emphasize: the birds themselves or their singing!
