Fish die by botulism, birds eat infected fish; a likely story. The timing is a little off-putting, though. Why can’t we just admit that the grief-stricken, poor economy-shaken birds committed mass suicide? By the way, if you live on Georgian Bay and awaken to hundreds of dead birds in your yard, don’t just start cleaning them up, contact your municipality first. Something might be up.
Unrelated, I urge you to play the internet’s greatest version of the game Telephone, Doodle or Die, but also to draw/say something other than a penis or a Nazi when it comes up, as well as the same for any Homestuck references. Those are just far too common on the site.
