Well, it looks like the storm was too much for the birds. This morning, after the last bit of rain stopped, I noticed the parent bird bring food to the nest as they have been doing over the past 1-2 weeks. But then the bird would come back out of the nest with the food still in its beak. This happened a few times, so I peeked into where the nest is located and the nesting birds were motionless. After several hours I checked again. No-go.
I noticed the parent bird coming to the nest once more, but now it appears the parent bird(s) are no longer frequenting the nest.
I am wondering if the wind-driven rain caused hypothermia of the nestlings.

Overall, from what I can see the birds looked healthy and were growing quickly. The parent birds were bringing a constant supply of food.
I had planned to delay launching the boat until the birds had left the nest. Looks like nature had other plans.
