Nestbox Trail Statistics
This collection of trails is a combination of those which have existed for many years, newly established or refurbished trails, and expanded trails.  The productivity shown below is the result of the dedicated efforts of the many members of VBS, and a lot of hard work by a lot of great birds.

The increases in year over year reflect more and better nest boxes, good monitoring programs, and probably more producing birds due to prior year successes.
