This question comes up every time a Bald Eagle lays an egg, and one person’s answer isn’t always the same as another’s. Fortunately, we now have a sizable body of data that provide a reliable answer.  Information collected from JudyB’s charts, the Hancock Wildlife Forum, the Channel Islands EagleCAM Forum, nest cam websites, and other observations give reliable dates and times for 55 nests with 2-egg clutches, 37 nests with 3-egg clutches, and 1 nest with a 4-egg clutch.

The eggs come at roughly 3-day or 4-day intervals. But the data tell us much more than that.

Go here to see the data and my analyses. And let’s have a conversation on Facebook about it.
