Hi there. I have been birding most of my life and am currently a grad student working on a bird migration study. "A bird does not sing because it has an answer. It sings because it has a song."

Sparrows change their tune to be heard in noisy cities
ScienceDaily (Apr. 2, 2012) — Sparrows in San Francisco’s Presidio district changed their tune to soar above the increasing cacophony of car horns and engine rumbles, details new Mason research in the April edition of Animal Behaviour.
“It shows a strong link between the change in song and the change in noise,” says David Luther, term assistant professor in Mason’s undergraduate biology program. “It’s also the first study that I know of to track the songs over time and the responses of birds to historical and current songs.”
