Rick Wright, Managing Director of WINGS Birding Tours Worldwide, writes:
Not much mystery to the identification of this mystery bird: anyone who recognized in this bird’s large body, sturdy feet, long neck, and conical bill the classic marks of a goose will also, more or less immediately, have identified it as the distinctive, even unmistakable, Hawaiian Goose. Nearly extinct three quarters of a century ago, the species has recovered somewhat, largely thanks to captive breeding and release programs, and can once again be seen on the lava slopes it so greatly favors. Among the adaptations for its dryland lifestyle: if you look closely, you’ll see that the toes of the Hawaiian Goose are only partly webbed.
