Nesting Preferences of the Black-capped Chickadee - A Citizen Science Opportunity
Black-capped Chickadees are cavity nesters. This means chickadees like to nest in the cavity of a tree. They prefer to excavate their own home but have been known to use old Downy Woodpecker cavities. When excavating their own home, chickadee's look for the soft location on a tree such as where a branch has fallen off a tree, often in dead alder or birch snags. They will nest in a suburban backyard, a rural park or in a natural forest.
We want them to nest in our backyards but we don't often have dead alder or birch snags as part of our habitat. We sell nest boxes sized for Black-capped Chickadees and we have always recommended the box be filled with wood chips to allow the chickadees to excavate their home. Unfortunately, success is not as common as we would like. We have always kept an eye out for any information that would help improve nesting success. In the late spring of 2014 we became aware of studies regarding Black-capped Chickadee nesting behaviour conducted by Cornell Lab of Ornithology in 2008. Kyle Holloway, our store manager, and myself were intrigued by the results. The results of the study indicated chickadee nest boxes made form PVC tube and filled with wood chips were the most successful. Click here to get the full details.

Kyle constructed a number of PVC Chickadee nest tubes for testing. They were placed in yards early that summer. We did not have success, but we believed the nest tubes were installed too late in the season for a fair and accurate test.
We made sure we were ready with nest tubes for the spring of 2015. One nest tube was installed in Kyles yard, his parents yard and we had one in our yard. A number of the PVC nest tubes were set-up in Algonquin Park. We had good success. Kyle had a Red-breasted Nuthatch nest in his tube and his parents had a Black-capped Chickadee nest in their tube. Fledging was successful for the the two nests. Our PVC nest tube was inspected by chickadees but never used. The Algonquin PVC nest tubes were excavated but no other details were available. The overall results were exciting. We decided to expand our local study for 2016.
Kyle has taken on the project of building PVC Chickadee nest tubes to sell in the store. We have developed two styles. One is designed to sit on top of a pole based on our Advanced Pole System and the second style uses two cable wraps to allow placement on an existing tree trunk or pole.
PVC Chickadee Nest Tube Pole Set-up - $49.99 (includes APS mounting flange)
