With slightly more than 500 listings (80 animals and 424 plants), Hawaii is the nation’s hands-down endangered and threatened species capital. Largely responsible for that ranking: island isolation and pests.

In the sad case of the iiwi, or scarlet honeycreeper, an invasive mosquito is a culprit, restricting the bulk of the bird’s population to a narrow forest area on East Maui and on the windward side of Hawaii island above 4,265 feet. Iiwi are now climbing to that cool elevation to escape the mosquito’s reach — and avian malaria infection.

Here’s hoping a recovery plan can bring the bird with the distinctive down-turned bill back to lower elevations, where it once flourished.

Health care proposal can make a person ill

When people who eat, sleep and work the complex system of government help with health care costs are feeling worried, we all should fret a bit.

The proposed radical reshuffling of federal health care funds will tend to hurt states disproportionately that expanded Medicaid. States like Hawaii.

“I’m not sleeping,” she said. We can all feel a little sick now.
