[Toucan]

Flock was a web browser until last year: http://en.wikipedia.org/wiki/Flock_(web_browser)

I know there are only so many names, but in this case both flocks are social apps, tracking updated photos between friends.

I wonder if Zynga (the owners of flock.com now) will have anything to say about this, though I find it hard to imagine it hasn't already been discussed.
