Bluebird Trail

2012 Nesting Season Report

The volunteer monitors checked on 66 boxes, and backyard birders checked 25 boxes this season for a total of 91 boxes monitored this year. Of the 91 boxes monitored, 68 boxes had activity (or an attempt – defined as nest building activity or more). Three boxes had successful Western Bluebird double clutches: N 19 and S 13 at Indian Hill, and one of Jennifer’s backyard boxes.

There were six species nesting in the boxes, Western Bluebird topping the list with 62 “tries” or attempts, resulting in 265 eggs, 228 young, and 191 fledglings. This ranks as the third largest number of Western Bluebird fledglings out of the 13 nesting seasons of monitoring, just edging out the last two years 2011 and 2010 with 187 and 183 fledglings respectively.

One of Mary’s backyard boxes produced a successful nest attempt of White-breasted Nuthatches. The first for our records!

Congratulations on a very successful nest box monitoring season!!! I’m sure the birds would thank us if they could.

If you are interested in being a monitor next year, or want to monitor a box in your yard, please contact me! It's fun!

Thank you all!
Karen Pestana, Bluebird Trail Chairman


Background Info

Bluebird Trail MonitorsIn many parts of the country bluebird numbers have decreased dramatically due to competition for nesting cavities with the European Starling, an aggressive non-native species. Each year local volunteers maintain and monitor a "trail" of nest boxes. During the mating and nesting season (February through July) we monitor the nest building, egg laying and fledging of the young Western Bluebirds. Records are forwarded to the North American Bluebird Society.

Anybody wishing to install a bluebird-nesting box on their property, or those who would like to join the bluebird trail monitoring teams, please e-mail Karen Pestana, Bluebird-One, or call 821-6477.
