The Bluebird Trail Last updated 10/19/12

What is a Bluebird Trail? It is a series of bluebird nesting boxes, set up at appropriate intervals in keeping with the bluebird's territorial requirements. Bluebird trails have been established in many areas and are monitored by volunteers to maximize nesting success and record data on nesting box usage and the results of nesting attempts by both bluebirds and other species. Over the years, bluebird trails have played a major role in bringing bluebird populations back after they had been decreasing for many years. For more information on bluebird trails throughout the United States, and to learn what you can do in your own yard for bluebirds, check out the North American Bluebird Society's website or the New York State Bluebird Society's website.

POLES AND PVC PIPE NEEDED - PLEASE DONATE!
As of May 2011, the Ralph T. Waterman Bird Club monitors 16 Bluebird Trails and 203 nest boxes throughout Dutchess County on public and private land.  We are always seeking to establish new trails.  Nest boxes are mounted on metal poles that are 1 1/2” – 3” in diameter and are 6’ – 7’ long. Each pole is inserted 18” – 24” into the ground with a PVC pipe approximately 4” in diameter and 30” long mounted below the nestbox as a predator guard.  We are always in need of used donated metal poles and PVC pipes. We can pick up donated material.  Please contact to donate. Thank you.

Florence Germond began the Dutchess County Bluebird Trail in 1962 and continued to coordinate it until her death Oct. 13, 1994. During the first year, 1962, 4 boxes were not used, one was damaged, and one was stolen. In the one box used by bluebirds, two broods were raised.

Peggy Fasciani was coordinator in 1995, Dorcas Brower was coordinator from 1996 through 2009, and Susan Gilnack has been coordinator since 2010.

You can browse the data below to see what a difference the Dutchess County Bluebird Trail has made over the years. Please see the explanatory notes at the bottom of the chart.

Notes:
Numbers in red are counts of boxes used; numbers not in red are individual bird counts.

Second (and occasionally third) broods count in eggs / hatched / fledged numbers but only once in box count.
Many more boxes are mounted than monitored, and some monitored were not used.
Non bluebird usage not accurately tracked in most years.
Average bluebirds fledged per box based on total number of boxes monitored, whether used by bluebirds or not.
