times are local time at the nest
If the cam doesn't look into the nest bowl, the hatch date for the first eaglet is based on the behavior of the parents and that of subsequent eaglets is 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; nests may only be checked once a week after fledging, so the fledgling may have been around for several days after it was last seen on cam by us.
I use 35 days from the date the egg was laid as a time to begin to look for a hatch; the first egg often hatches 37-39 or even 40 days after it was laid; the middle egg of three is often 36-38 days; and the second of two or third of three is often 35-36 days - but 34-40 days is not unlikely, and 33-41 might be possible.
Please check About the Nests for more information about the history of the various pairs and pictures of the nests.

The pair failed in their attempts to build a nest, and ended up laying two eggs on the ground; by the time this nest was discovered by Bev and Ralph from O.W.L., one egg had broken. The second was removed for incubation, but candling showed that while it had been fertile, the embryo had died. |

2 eggs laid in late March; 1 broke, the other apparently died after a couple of weeks |

A large part of the nest gave way before the start of the nesting season. The pair made some efforts at rebuilting, and some efforts at starting a new nest, but didn't make progress with either and didn't nest. |

Noah apparently stayed in the area for a few days, then headed north within a week or so. CRC reported May 19 that she was in Virginia, in an area frequented by other eagles (good for learning how to hunt and scavange). |

Moved to a new nest for 2010; cam was moved as well new nest is former hawk nest it was very windy when the 2-day old chick crawled through a hole at the edge of the nest; it's possible the chick was partially blown to that area as chicks that young rarely move about the nest older eaglet was beginning to stand upright and likely lost its balance and stepped over the edge while trying to regain it |

NOTES "Pigeon Forge, TN, April 14, 2010 -- Two Bald Eaglets recently hatched in an incubator at the American Eagle Foundation's United States Eagle Center at Dollywood in Pigeon Forge, TN. At 3-days old, the eagle chicks were placed in the nest of captive non-releasable Bald Eagle pair "Liberty" and "Justice" for adoptive rearing until they reach 6 weeks of age. At that time, the eaglets will be placed into an artificial nesting tower over-looking Douglas Lake in Dandridge, TN, where they will be cared for by AEF staff until they are released into the foothills of the Great Smokies at 12 weeks of age (when they reach full size)." - from the American Eagle Foundation website
