Peter and Linda report 4 fledglings below dam just above Bridge 1 being fed by the male. No sign of Bridge 1 female. Photo by Peter below.
Bridge 3 male and female continue to feed at the nest and build their second nest in the adjacent box. Bridge 3 is the only Bridge with 2 boxes due to a slight design change. The original box is made with some plywood and the newer box is cedar.
