How much is that birdie in my backyard?

In a recently published article, Clucas, Rabotyagov, and Marzluff report:

Human-wildlife interactions in urban areas, both positive and negative, often involve people and birds. We assess the economic value placed on interactions with common native songbirds in two different urban areas (Berlin, Germany and Seattle, Washington, USA) by combining a revealed preference (recalled expenditures on bird feed) and a stated preference approach (determining willingness to pay for conservation or reduction of birds). Residents in both cities purchase bird food, engage in a range of bird-supporting activities and are generally willing to pay a small amount for native songbird conservation. Demographic, cultural and socio-economic factors, as well as specific attitudes towards birds and general attitudes about conservation were found to influence these decisions. This study presents the first attempt at estimating the economic value of enjoying common native urban songbirds and estimates the lower bound to be about 120 million USD/year in Seattle and 70 million USD/year in Berlin.

There is some media coverage here, and for the pointer I thank Charles Klingman.
