GDA members and others have worked closely with Lafarge to install and monitor a number of bluebird boxes on one of their large end-use pits. Volunteers visit the site several times each birding season to conduct bird counts and report that the houses are a big hit!
The results of our bird surveys at this restored gravel pit:
Bird Occupancy in Nest Boxes at Lafarge Gravel Pit
100% would indicate all 48 possible boxes were used.
We estimate 850 swallows, 290 bluebirds, 30+ chickadees and 55+ wrens were raised over nine years!
2022 saw a 92% occupancy rate for our nest boxes. A recent survey revealed over 35 different bird species breeding throughout the semi-restored gravel pit area including seven sparrow species. We are especially pleased to report that the Grasshopper sparrow, a species listed as “at risk”, has returned to this area The success of this restored aggregate pit demonstrates that nature needs these restored forests and grassland areas. If you build it they will come!
