A special group of volunteers have been helping the York County Parks maintain bluebird nest box trails since 1999. Eastern bluebirds, Sialia sialis, are frequently seen in Pennsylvania but this was not always the case. In fact, around 1950, bluebird populations began to decline, mainly due to loss of suitable nesting sites resulting from habitat destruction, competition from non-native species, and an increased use of pesticides. Fortunately, people took notice and began to build bluebird-nesting boxes to help increase the bluebird population.

     Currently, bluebird boxes are located in suitable habitat in John Rudy County Park, Nixon County Park, Spring Valley County Park, Rocky Ridge County Park, and along the Heritage Rail Trail County Park. The volunteer landlords are responsible for monitoring the bluebird nest boxes, beginning in April through the end of August. Bluebird monitors typically visit their boxes once a week checking for signs of nest building.

     How good is it living rent-free in the York County Parks? Since 1999, park volunteers have been landlords to 712 bluebird hatchlings and their parents. Of those hatchlings, 663 bluebirds have left the nest.

     Why become a bluebird landlord? The reasons vary: whether part of a fitness program, an excuse to take a break and go outside, an opportunity to connect with friends and family, a way to introduce youngsters to nature, or as Bob and Deanna Holtzapple, veteran bluebird landlords, said, “This is something we can do together. We both love nature.“

     In 2008, 11 bluebird volunteers will monitor about 55 bluebird boxes. For all of their efforts, on behalf of the York County Parks and all the park visitors who have enjoyed seeing the result of their efforts, we would like to say thank you to all the former and current bluebird landlords.
