The group, BC Purple Martin Stewardship & Recovery Program, is looking for areas in the Lower Mainland / Upper Fraser Valley to start colonies of purple martins in their historic range.
They estimate there are about 450 pairs in BC, which is up over double from 200 pairs in 2002. A very good and successful nesting season this summer promises even more next year.
The Program is looking for areas with snags that are away from the tree canopy, such as over a lake or wetland. They will place boxes, but the intention is that after they become established, boxes will slowly be removed to encourage nesting in natural cavities.
Please post any sites you think may be suitable to help with these efforts. I have recommended Cheam Lake Wetlands. There was a spring sighting there in 2003; likely a bird looking for nesting according to the study team.
