At DuckDuckGo we are averaging roughly 17 million searches a day right now (duckduckgo.com/traffic.html)
Google says they did 2 trillion searches last year[1], and while usually their search metrics include Youtube, Google Maps and Gmail queries let's assume it was all searches. That'd be roughly 5.5 billion searches a day.
So now we're talking ~1/322 or just shy of 40lbs. That's roughly the size of a Hamadryas baboon or about 22 Mallard ducks - not a bad little flock! :)
