The REAL Twitterers

A family of wrens has taken up residence in our back yard, and after a short time of watching and listening to them, it's pretty clear why a cartoonish wren is the symbol (mascot?) of Twitter, the website:

• The word "twitter" is very much an onomatopoeia for a wren's warble. (If you're not familiar with their song, you can hear some in this short video.)
• They're very small -- less than 5 inches long -- kind of like 140 characters is a small amount of space.
• But despite their size, they crank out the volume. The decibel level coming from such a diminutive creature is truly impressive. I could hear them over the sound of the power mower!
