What is this Creepy Sound? Ewa Beach, Hawaii

We had been trying to find the source of the creepy noise for a few days. We thought it could be a cat, but there’s are lots of noises in our neighborhood, and it can be hard to tell what or where the noise comes from. There are many children around and people often have their windows open so sounds drift through the neighborhood. At one point Wendi crept through the street trying to localize the noise, honestly thinking there was a chance there was an abandoned baby in the dumpster, or a dying rabbit, or a mother cat giving birth…maybe a lamb caught in a trap.

We finally tracked down the sound one night while relaxing in the front yard.
