Summary of Eaglet Information

Last Updated January 25, 2014

the symbol ~ is used to mean approximately
the symbol < is generally used to mean before or earlier than

If the cam doesn't look into the nest bowl, the dates for the first eaglet is based on the behavior of the parents and those of subsequent eaglets are based partly on an assumption of 2-3 days between hatchings and partly on the number of days between sighting of the first chick and sighting of subsequent chicks; there may have been additional eggs that didn't hatch or hatchlings that only survived a day or two in those nests.

While I have observed many of these nests through the wonder of web cams, some of the information (especially in the earlier years) comes from the cam websites; I am also including the non-cam nests monitored by the Institute for Wildlife Studies on the Channel Islands off southern California because they are observed in a consistent fashion. Please see my Eaglet Information Tables (linked below) for more details on the various nests, cam links, pictures, etc.
