Robin's Nest

Robin's Nest

Ten days ago on June 19th, I discovered a Robin's nest in the rafters of the shelter of the Elbow Valley Constructed Wetland. There were two eggs in the nest on that day. I have checked the nest every few days. Either the nest has been empty or the mother has flown off with my approach. On subsequent checks I noted three, then four, and today five eggs. The average number of eggs is four, with a range of 3 to 5. Mom is likely finished laying. Incubation will last 11 to 15 days. 
This, I believe is Father Robin, based on proximity to the nest and the simultaneous presence of the Mother Robin on the nest.
Incubation is only by the female, who looks settled on her five eggs.
