Islands

Are you a threat to the west
Sticking out your chest
Are you a threat to the west
Protecting your nest

Are a threat to the west
Sticking out your chest
Is protecting your nest
A threat to the west

Feathers that grew from your wings
These things you were born into
Whether you choked on that food
Or spat some sugar in my bowl

Swallow swallow
Someone would be swallowed whole

Are you a threat to the west
Sticking out your chest
Are you a threat to the west
Protecting your nest

So sing a song for me
A swallow sitting on a tree
No words doesn't mean
No harmony
It's coming to hear you breathe

Are you a threat to the west
Sticking out your chest
Are you a threat to the west
Protecting your nest
