There was too much noise in this nest to be able to make any predictions. Very early -- day 51. 20+ emerged the following day. No obvious explanation for all the noise. The sensor had moved from its installation position in the nest. Might be a faulty sensor.

The morning of 8/7 a hatchling was found wandering near the dunes. Rain washed out the tracks so it is not certain how many emerged the evening of 8/6. There was a record of 9 hatchlings on the 9th and 5 on the 10th. A total of 85 eggshells were counted. It seems likely that most of the hatchlings left on Thursday evening (8/6).

More than 20 tracks were counted the morning of the 8th. On 8/9 the activity recorded was from the nest being washed out. Very few hatched or unhatched were found after the washout, so it is unclear exactly what happened.
