20. www.christmasbirdcount.org The Conservation Value of the Christmas Bird Count is evident in the many projects resulting from use of these data

21. www.christmasbirdcount.org The Christmas Bird Count also shows the value of citizen science In the 106th Christmas Bird Count there was a total of 292,000 hours spent counting birds by all participants. At $16.54 per hour + 12% fringe = $5,405,907 or this is equal to 146 full time employees If you add the cost of miles traveled during the count: 575,000 miles * IRS rates = $209.857 This results in a $5,615,764 value to the work of bird conservation by citizen scientists in that one year!
