[Illustration: OU
(male)]
DESCRIPTION: 6½″. A greenish bird with a heavy _parrotlike bill_. Male:
Varying shades of green above, lighter below, with a _bright yellow
head_ that give it the appearance of being unusually large headed.
_Female and Immature_: Lack the yellow head.
PARK DISTRIBUTION: Kilauea—Rare; in the wet tree-fern jungle. Thurston
Lava Tube is within its range. Haleakala—Absent from Maui.
VOICE: A beautiful singer, according to Munro. Note: a medium
high-pitched _teweé_.
Ous are fairly inactive birds, often spending long periods quietly on
the branch of an ohia or other tree, and would be difficult to locate in
the dense forest except for the bright male plumage. They frequently
travel in pairs and apparently have a small individual range, for the
same pair may be seen day after day in one locality. Their food consists
of fruit.
