The mud dauber has sealed the open chamber and added another. Just looking at the structure, I believe there are three chambers total. I have
uploaded a new picture.

SukanyaDatta - Mahalo nui loa - thank you very much - for the links. The last one was remarkably detailed and educational.

SukanyaDatta - "The adult wasp lays an egg inside the pot and seals it...along with provisions. It does not enter." Thanks for reminding me, though I think I knew that--once upon a time; my brain is going fast.

SukanyaDatta - That was my first thought--and I don't have a second one! The only thing that bothers me is that I've never seen a wasp small enough to get through a 3mm hole.

Tom: Thanks for the ID.

UPDATE: My eight year-old granddaughter hand pollinated one of the flowers, and there is now a pod on the tree with at least one seed in it.

Some research suggests these fungi might be the fruiting bodies a species of sporangia, such as Arcyria sp. or Bedfordia salicina.

SukanyaDatta - Thanks for the feedback, and for the information on the neck ring. Today I tried to capture additional images of one of these birds and did so, but I was reduced to shooting through a window with a long lens. Any attempt to go outside frightened the birds off. I have posted crops of two of today's images as the fourth and fifth of this spotting. In each of those images a neck ring appears to be present.

Thanks for the ID suggestion Kalen. However, the Purple gallinule, Porphyrio martinicus (actually, the American Purple Gallinule, Porphyrio martinica (Linnaeus 1766)), has not been observed in Hawaii. This spotting is in fact an Hawaiian moorhen, Gallinula galeata sandvicensis.

Sukanya Datta: Thanks for the link. Yes, similar. There were several of what appeared to be the species at your link in the vicinity of this spotting. The botanical gardens at Waimea Falls Park have a large heliconia and ginger collection.
