Hi Birders, Here is a volunteer opportunity that is kinda neat: online data entry of historic migration notes across the nation from the 1880s to 1970 (see below). It provides a interesting glimpse into to history of North American birding before the computer age, and a look into the changes in dates of arrivals of wild birds. It is pretty easy to participate, and I recommend watching the instructional video if you sign up.
The website is: http://www.pwrc.usgs.gov/bpp/index.cfm A nice scientific use of the Internet! Best, Scott Severs Longmont More details from the website: "The North American Bird Phenology Program houses a unique and largely forgotten collection of six million Migration Observer Cards that illuminate migration patterns and population status of birds in North America. These handwritten cards contain almost all of what was known of bird status from the Second World War back to the later part of the 19th century. The bulk of the records are the result of a network of observers who recorded migration arrival dates in the spring and fall that, in its heyday, involved 3000 participants. Today, those records are being processed and placed into a modern database for analysis. This information will be used, along with recently collected arrival times of migrant birds, in conjunction with historical weather data to show how migration is affected by climate change. The information from this analysis will provide critical information on bird distribution, migration timing and migration pathways and how they are changing. There is no other program that has the depth of information that can help us understand the effect that global climate change has on bird populations across the country." --~--~---------~--~----~------------~-------~--~----~ Join us at the 2009 Convention in Alamosa: http://cfo-link.org/convention/index.php You received this message because you are subscribed to the Google Groups "Colorado Birds" group.
