| Description:
Adult:
The head is a soft blue-grey, with
a slight greenish-purple gloss on
the nape. The feathers of the sides
of the neck are rather stiff and arranged
in lines forming the characteristics
furrows seen in many species in the
genus. These feathers are strongly
glassed with green to purple iridescence.
Below this is a large and distinct
patch of white-tipped feathers. The
greenish-purple gloss of the hindneck
fades into a brownish-grey mantle,
inner wing-coverts and tertials. Remaining
wing-coverts are grey except for the
outer three or four which are white,
forming, with the distal lesser coverts,
a bold white crescent on both the
closed and open wing. Alula and primary
coverts are balckish. Flight feathers
are dark brownish-grey, each primary
variabley fringed with white along
the leading edge of the outerwebs,
especially basally. The back, rump
and uppertail-coverts are blue-grey
shading into the grey tail-base. Tail
has an ill-defined broad blackish
apical band, less distinct on the
outer feathers. The throat and chin
are soft blue-grey like the head,
but often slightly paler. The breast
is vinous-pink grading into paller
pink on the belly and pale grey on
the vent. Undertail-coverts are pale
grey, and slightly darker on the belly.
Undertail dark grey basally with a
clearly demarcated blackish terminal
band, broadest on the central feathers
and with a broad, pale grey median
band. Then underwing-coverts are blue-grey.
The iris is pale yellow. Orbital skin
is greyish, not readily visible in
the field. The bill is yellowish with
a paler tip and reddish base; the
cere is white. Feet are purplish-pink.
Juvenile: Much duller and browner
than the adult, lacking the glossy
colors and the white neck-patch because
iridescence is acquired with age.
Wing-coverts have narrow buff fringes;
white on the wing-coverts is duller.
The vinous coloring of the breast
is duller and more restricted to the
foreneck. The iris is grey, tinged
yellow. The bill is yellowish with
a darker tip and a brownish-red base;
cere is brownish-grey. The feet are
slate-grey tinged with purple.
