the symbol ~ is used to mean about or approximately; the symbol ≤ is used to mean on or before
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.

not completely sure what happened, but there was a bad storm shortly after the eggs were laid, and the female was away for a couple of days; when she returned she didn't resume incubating, and the nest was eventually left untended, and subsequently failed. Maybe next year.... |
