Bristle-thighed curlew (Numenius tahitiensis) isn’t the most flattering bird name I’ve ever heard. In Hawaii it’s called Kioea, which sounds nicer. In May, these curlews migrate to Alaska (a jaunt of 2480 miles) to breed. They return to Hawaii (and other Pacific islands) in July and August. Since this particular bird was still around at the end of May, it may not be making the trip north this year.
