Speaking of tweeting, lately I've been hearing a chorus of bird chatter outside my window very late in the evening. Their timing strikes me as somewhat odd; surely birds of the tweeting variety are diurnal, for the most part? I was always under the impression that nocturnal sounds were left to the owls and other hooting creatures of the night. Even now, I hear the birds chirping away as I type.
A quick Google search later and I find that what I'm hearing isn't so strange. According to the Boreal Songbird Initiative website, I'm just bearing witness to the birds' musical migration:
"On spring nights, while most people are sleeping, a river of migrating birds flows north from wintering grounds in South and Central America and the Caribbean towards the places where they will raise their young in the Boreal forests of Canada. Few people realize that most birds migrate at night and that the number of birds making this phenomenal journey number in the billions."
Who knew? Reason #9439 why I can't live without the internet.
