Marshall, 1945 Palau Rhynchura rufifrons wide. This usually when a pair is together & lone as display. The bird parades around awhile with tail high over back & spread to maximum, then closes it & goes back to foraging. Very tame & curious. Usually met with in this unfailing pattern. You're walking along a trail & suddenly you hear the twanging scolding notes of 1 or 2 birds dash up, hop around you awhile looking at you, then off they go to forage. Strikingly different in notes, size, coloration from Marianas birds. Difference also in manner of fanning tail & I believe combined with its large size is a loss of some of the nimbleness & rapid moving of the little Marianas birds. I wouldn't be surprised if the former actually weighs twice as much as the latter.
