Wetlands Nesting Box Project

A pair of Tree Swallows claimed this nesting box, located adjacent to pond A-2 near the effluent discharge point in Moorhen Marsh, as their very own – April 17, 2015. Tree Swallows are cavity nesters. Boxes like this one become increasingly important when snags and dead branches are removed from landscapes.

MVSD has installed nesting boxes for the following bird species in the marsh system:

  • American Kestrel
  • Barn Owl
  • Tree Swallow

As of July 2016, the American Kestrel and Barn Owl boxes have not attracted any nesting pairs, but the Tree Swallow nest box program was a hit from the start!

In November 2014, consulting biologist Jeff Alvarez’s company, The Wildlife Project, donated 14 Tree Swallow nesting boxes for use in the District’s wetlands. Along with the nesting boxes, hardware, and poles, Jeff’s crew also provided approximately 16-hours of volunteer time in March 2015 installing the boxes throughout the marsh system. Within hours, several of the boxes had residents and by April 20th all boxes were occupied!

We Need More! Pack 420 Builds Tree Swallow Nest Boxes for MVSD’s Wetlands

On Saturday, July 11th, 2015 District Biologist Kelly Davidson and consulting Wildlife Biologist Jeff Alvarez provided a 2-hour program for Cub Scouts and their parents from Pack 420. The program provided instruction and materials for building Tree Swallow nest boxes for MVSD’s wetlands. The program also helped the Cub Scouts earn a badge in conservation. The 14 Tree Swallow boxes installed in Moorhen and McNabney marshes in February of 2015 were all occupied. Thanks to Pack 420, MVSD added 10 additional Tree Swallow boxes for the 2016 nesting season!
