In its simplest form, the pigeon repeats a three syllable phrase which could be “I love you. I love you…”
When the pigeon extends its call to five syllables it should be “I really love you. I really love you …”
But listen carefully, the infuriating bird clearly thinks of the phrase differently it finishes on the “I“ so it’s more like “Really love you - I. Really love you - I …”
Nature is wonderful.
