The site is one of only a few known locations in the western U.S. where large numbers of diurnal (daytime) raptors, songbirds, and forest owls funnel during fall migration due to its unique geography and habitat mosaic. Woodland birds tend to ‘pile up’ on Lucky Peak to feed and rest before crossing the 50+ mile expanse of the Snake River Plain on their southbound migration. This natural phenomenon presents a unique opportunity to study the migration of many different birds in one location. From mid-July through October, research station staff and volunteers run a 24/7 fall migration project that includes banding of songbirds, diurnal raptors, and owls, as well as a Hawkwatch monitoring station. Each fall, Lucky Peak crews capture and band between 4,000–7,500 songbirds of about 60 different species, about 1,000 hawks and falcons, and as many as 900 owls. Observers at the Hawkwatch station count 5,000–9,000 raptors of 18 different species annually. These banding and migration studies provide important data on bird population numbers, age and sex ratios, reproductive success, breeding timing, migration movements, and individual bird longevity. This information is used to study the impacts of climate change, the importance of different habitat types, and changes in species populations.”

The island was the breeding ground for about half of Hawaii’s endangered green sea turtles and 30% of Hawaii’s highly endangered monk seals. When scientists recently examined satellite photos after the hurricane they discovered the whole half-mile long 400 ft wide island had vanished. Over time, when sea level is stable, storms, swells winds and overwash create islands.  The northwest Hawaiian islands were once large islands like the main island, but erosion and the cooling and sinking of the crust submerges the volcanic bases of all of the islands over periods of ten million years of more. However, coral and coraline algae growing on top of the volcanic core have been able to maintain islands long after the volcanic base submerged. That is, until now.”
