It's for the birds
Date:3/18/2009

On Nov. 1, 1933, Mrs. Bruce Reid recorded seeing both a male and female ivory-billed woodpecker in Texas. And on May 28, 1938, Oscar McKinley Bryans observed a ruby-throated hummingbird in Michigan, noting that the birds were most common when apple trees were blooming.

These are just two of more than 6 million personal observations scribbled and preserved on notecards in government files. The cards record more than a century of information about bird migration, a veritable treasure trove for climate-change researchers because they will help them unravel the effects of climate change on bird behavior, said Jessica Zelt, coordinator of the North American Bird Phenology Program at the USGS Patuxent Wildlife Research Center.

That is -- once the cards are transcribed and put into a scientific database.

And that's where citizens across the country come in the program needs help from birders and others across the nation to transcribe those cards into usable scientific information.

"These cards, once transcribed, will provide over 90 years of data, an unprecedented amount of information describing bird distributions, migration timing, and migration pathways and how they are changing," said Zelt. "There is no other program that has the same historical depth of information that can help us understand the effect that global climate change has on bird populations across the country. When combined with current information, scientists will better understand how birds are responding to climate change and how to develop tools to help manage that change, especially for at-risk species."

The millions of hand-scribbled cards sit in row upon row of federal green filing cabinets of ancient vintage in a modest and fittingly old office dating from before WWII. The cards contain almost all of what was known of bird distribution and natural history from the Second World War back to the later part of the 19th century, said USGS senior scientist Chan Robbins,
