Highway engine noises rumble, babble, bang
Bird wings flutter, whish, whir
Nest chirp noises beg, chorus, crave
Non-stop until one by one chirps cease
Highway engine noises roar, growl, grumble
Bird wings pulsate, flap, flurry
Nest chirp noises warble, clamor, chirrup
Non-stop until food stills each peep
Highway sounds
Wing commotions
Nest twitters
Again
And
Again
