Bluebird Nestbox Monitoring
Why Do We Monitor Bluebirds?
Beginning in the early 1900s, Eastern Bluebird populations underwent such a precipitious decline that many feared extinction was inevitable. Reasons for the decline included loss of habitat, pesticide use, and the introduction of House Sparrows and European Starlings into America. Both species are cavity nesters (as are bluebirds) and are extremely competitive and aggressive. In 1978 the North American Bluebird Society was formed by citizen scientists to promote the conservation of bluebirds and other native cavity nesters. They set up a network of bluebird nestbox trails, educated the public and trained volunteers as monitors. As a result, Eastern Bluebirds have made a comeback.
Loudoun Wildlife Conservancy volunteers monitor nestbox trails throughout Loudoun County. By monitoring the boxes, we collect information on our native cavity nesters, learn about their lives first hand and track population trends. The data we collect is submitted to the Virginia Bluebird Society.
How to Get Involved
Monitoring at our public trails is done in teams of four so that each person monitors about once per month, April though August. Each trail has a trail leader who creates the monitoring schedule, trains new monitors, identifies trail repairs and compiles the data at the end of the season and sends it in.
Alternatively, you could set up and monitor your own home trail once a week through the season. At the end of the season, compile the data and send it in.
Nestbox building/repairs and trail set up
A great project for scouts or school groups is to build nestboxes and set up a Bluebird trail and then let us monitor them. We also need help with existing trails that need box replacement.
If you’d like to help with monitoring or maintenance, please sign up here. All levels of experience are welcome. Training will be provided.
Loudoun Bluebird Notes is published online for our nestbox trail monitors. The newsletter has articles about cavity nesters, trail monitors, and tails from the trails along with beautiful photographs from our contributors. In addition, the newsletter offers tips on how to deal with predators and provides answers to frequently asked questions.
