While scientists have worked hard over the last three centuries to describe and classify living organisms such that each distinct species would be known by a unique name, there are many species which have more than one (and in some cases, several) common names. This isn’t really surprising since scientists use Latin as the language to apply official scientific names and regular folk like to use the regionally common name they have always used.

Colloquial names have also arisen from a tradition of long local usage and the publication of official names, as endorsed by a panel of eminent scientists who live somewhere else, is not going to end the use of colloquial names.

It’s one of the charming eccentricities of birdwatching that two birders can be arguing about some aspect of two similar birds, only they don’t realize they are discussing the same bird because they are referring to it by different colloquial names. Granted, this doesn’t happen very often anymore as the common names are becoming more standardized, thanks in large part to the explosion of bird guides that have been published over the past 50 years.

However, there are people who still refer to birds by their more colourful colloquial names. Here’s a list of the more commonly encountered colloquial names (in capital letters) along with the equivalent name that is used in bird guidebooks. (This list is based, in large part, on the names  recorded in The Birdwatcher’s Companion by Christopher Leahy)
