The phrase "Why do birds suddenly appear" comes from the song "(They Long to Be) Close to You," written by Burt Bacharach and Hal David. The song is a romantic soft pop ballad popularized by the Carpenters in 1970. The lyrics poetically express the idea that birds appear and stars fall whenever the person's romantic partner is near, symbolizing how the partner is so special that even nature seems to react to their presence. The birds "suddenly appear" as a metaphor for attraction and closeness to the loved one.
The song lyrically suggests that birds appear every time the person is near because they, like the singer, long to be close to that special someone. It is not meant to be taken literally but as a poetic image of deep affection and magnetic attraction.
In summary, the "birds suddenly appear" line is a poetic device from a love song symbolizing the natural world's response to love and closeness.
