Boulder County Bird and Wildlife Monthly Inventories
BCAS members Gillian and Alex Brown have been compiling the data for these inventories since June 1985. What a wonderful database they have provided for our county! (Thanks also to previous compilers Bill Kaempfer, Freeman Hall and Tom VanZandt.) The data comes from two sources: 1) A core of volunteer wildlife observers who faithfully submit monthly reports; and 2) COBIRDS. The inventory in full for each month can be found only on the web site, although the summary and list of contributors can be found in the BCAS newsletter as well.
