Upcoming Workdays

Bluebird Box Monitoring

Saturday, March 24

9 am-1 pm

The Eastern Bluebird, once threatened by invasive nest competitors and disappearing habitat, has experienced a remarkable comeback in last part of the 20th century thanks to human established and monitored bluebird trails and nest boxes. In the hope of attracting bluebirds to the Wissahickon’s restored meadow habitat, Friends of the Wissahickon has created two Bluebird trails; one in Andorra Meadow and one in Houston Meadow. The trails and boxes are proving to be successful at attracting bluebirds and other cavity nesters, as confirmed by our 2017 monitoring program.

FOW is looking for committed volunteers to assist in monitoring and maintaining our bluebird trails.  Attend this workshop and you will not only learn how to monitor a bluebird trail, but you will be a part an important citizen science data collecting mission to determine just how successful our bluebird trails are. This workshop will be mostly indoors with an outdoors portion and will last for about 4 hours in which time we will cover all aspects of bluebird box monitoring, including practicing monitoring a few boxes in Andorra Meadow.

Volunteers will learn how to identify a variety of bird species’ nests, how to safely monitor and maintain a nest box, what data to collect, and how to record it. Volunteers are required to commit themselves to 3-5 monitoring sessions throughout the 5-6 month breeding season and be responsible to report the data they collect to FOW.  A monitoring session takes about 2 hours and will consist of hiking approximately 2 miles through both Andorra and Houston Meadow with a short drive in between. Regular monitoring is key to collecting good data, so volunteers should be prepared to monitor boxes in a variety of weather conditions throughout the Spring, Summer, and early Fall.
