A More Precise Record of Nest Duties

July 12, 2022

Eagle Kepr, one of our regular chatters on the Loon Cam, has been keeping a detailed record of nest sitting times, starting on July 1. It is posted online as an annotated spread sheet. It provides a great example of how the nest sitting is divvied up between the male and female, especially during the last week or so of incubation. I’ve used the data to create a graphic plot for those who prefer a visual aid over hard numbers. Pink is the female, blue is the male. You can see that Mom does all the nighttime sitting and at this late point in incubation she is covering two thirds of the nest duties.
