Sitting in the catbird seat

I was in the car this morning, and one of my favorite programs on NPR came on the radio. It's a short little thing, usually just 2 or 3 minutes long, but it's always so interesting! The program is called "Bird Note," and every episode describes something about birds. Wild or tame, big or small, common or rare, showy or drab - it runs the gamut. The narrator sometimes talks about the behaviour of the birds, or their environment, or their plumage. One particularly interesting one a few weeks ago compared how much effort it would be for a human to build a nest comparable to that made by a robin. (It would actually be really, really difficult!) Today's show was about a bird called a catbird. Actually, it was about an idiom in which the catbird features prominently - as you might have guessed from the title, the idiom is "sitting in the catbird seat."

I'd never heard this phrase before, but the narrator explained that this phrase means having an enviable position, the upper hand, or the greater advantage in a situation. And the reason it means this is perfectly explained by the behavior of the catbird.

Catbirds are American birds of the mimid family. "Mimid" is Latin for "mimic," and mimids are known for the vocalization abilities. Other mimids include thrashers, mockingbirds and tremblers. The catbird's standard call sounds roughly like a yowling cat, actually, though it can also imitate other birds. (It's alarm or warning call sounds startlingly similar to a male mallard.) There are two kinds of North American catbirds. The grey catbird is the most common, and is found across the US in all kinds of environments (rural, suburban and urban). They are medium-sized and dark in color, with the only notable coloration being a rust-colored patch under their tails. The other kind of catbird is the black catbird, which is found more in Central America and Mexico.

So what does the catbird do to deserve having an entire idiom phrased after it? The catbird (like many animals) relies on height to assert superiority or dominance. If a catbird feels threatened, it will go to the highest position it can find to call out its warning call. The higher that position, the more likely the intruder will back off. In addition, if two male catbirds are jockeying to be the top male in the area (and thus attract the best female), they will take gradually higher and higher perches, trying to outsing the other, until one is at the highest point. The bird who gets the highest is the winner. And, of course, the high perch from which he claims his victory is called "the catbird seat."

So there you go. Sitting in the catbird seat means getting the most advantageous position.

I love finding examples of how something science-related has worked its way into everyday life and language. Okay, so maybe this phrase isn't the most common, everyday phrase you'll ever hear. But now, if you ever do hear it again, not only will you know what it means, you'll also know where it comes from!

Anyone have any other suggestions for phrases or idioms that have their origins in science?
