It's Florence (My character not Florence Welch) trying to catch the bird under a cardboard box...
"But he sang louder and louder inside the house, And no I couldn't get him out. So I trapped him under a cardboard box. stood on it to make him stop. I picked up the bird and above the din I said "That's the last song you'll ever sing". Held him down, broke his neck, Taught him a lesson he wouldn't forget."
