Summary of Eaglet Information

Last Updated January 16, 2016

the symbol ~ is used to mean approximately
the symbol < is generally used to mean before or earlier than
starting in 2015, data in italics is not included in totals

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.

NOTES

*2008 Norfolk eaglet was deemed nonreleasable in 2009 and became a permanent resident at Wildlife Center of Virginia in April 2010
The percentages for "eggs hatched" and "eggs fledged" are probably a bit high as there may have been additional eggs that didn't hatch in a few nests without a view into the nest bowl.
For the purpose of this chart, I consider eaglets successfully released from rehab or hacking towers as fledged.
In 2015 there were several nests where the eaglets were doing fine at banding and afterwards, but there weren't any post-fledge reports - so while I suspect most if not all fledged successfully, I couldn't include them as I did not have documentation; the nests without eggs were ones with eagles in the area; if I wasn't fairly sure they hadn't moved off-cam, I didn't include them.
