Big Bend NP - east CBC

This entry is backdated to reflect the date of the count; these numbers are via the Christmas Bird Count web site and the 'current year' results (date of reference 2/18/2011). I've removed number/party hour for the sake of the blog format which already crunches the columns awkwardly.
