2011 Nest Box Season Overview

Boulder County Audubon Society volunteers once again monitored nest boxes for bluebirds and other species in 2011. This was the seventh year of collaboration with Boulder County Parks and Open Space (BCPOS) and the fourth year of collaboration with the City of Boulder Open Space and Mountain Parks (OSMP). With three new trails added in 2009, the program has grown to 11 trails of 6 to 13 boxes each, 106 boxes total. 22 volunteers checked nest box status approximately weekly from late April to early August.

Over 7000 nesting attempts have been reported to the database by Colorado monitors since 1997. Only Ohio and Pennsylvania have contributed more. (Denver Audubon has one of the largest monitoring programs in the U.S.)
