Ecology of Hawaiian Waterbirds

Loss of wetlands, invasive plants, and non-native predators pushed Hawaii’s waterbirds to the brink of extinction by the early 1900s, although population numbers have improved somewhat in recent decades with conservation efforts. Nonetheless, all Hawaiian waterbirds have global population sizes estimated around or below below 2,000 individuals, making them still highly vulnerable to extinction...

April 29, 2021

Kīlauea's summit eruption continues on the Island of Hawai‘i; Halema‘uma‘u west vent erupts lava into the lava lake, which was 227 m (744 ft) deep this morning, April 29. Gas emissions and seismic activity at the summit remain elevated. HVO field crews—equipped with specialized safety gear—monitor the eruption from within the closed area of Hawai‘i Volcanoes National Park with NPS permission.
