I'd only seen nighthawks once before, in the Nevada high desert. They migrate 7,000 miles from Argentina. Last evening before dark, there were at least 9 nighthawks overhead, feeding on insects. These birds look like large swallows/swifts, but fly erratically like bats in pursuit of food. Sometimes at the bottom of a dive they create a mini-sonic boom of courtship or territorial behavior.
Also in the night sky were the Perseids, the meteor shower Earth is passing through for the next few days. The night sky in this area is especially dark, with the Milky Way like a celestial highway directly overhead.
For many years during the now defunct Around the State Race in Hawaii, we would cross under the Perseids on the long fetch from Niihau to South Point on the Big Island. Turning South Point for the weather leg up the Ka'u Coast, things changed dramatically. The volcano Kilauea is in almost constant eruption, and short tacking up an active lava flow was the name of the game. The sulphur mist, steam, and the ever changing shoreline, not corresponding to any charts, made it challenging for the navigator.
