CRS and I put a trail cam out by one of the Woody boxes we have set out. Boxes are made from scavenged wood and our local Pitt Meadows secondary students put them together.
This box has no eggs or sign of having been visited but the camera clearly showed the birds have been checking it out for a couple weeks! Hope to get pictures of ducklings jumping out in the future. A couple other nests had down around the opening but no eggs, we'll be checking again in a few weeks.
