Male.—Upper parts, sides of head and neck, chin, throat, and chest 
blue, this color much obscured by gray, brown, and blackish tips to the 
feathers; lower breast, abdomen, crissum, and thighs deep chestnut, 
obscured by whitish tips and blackish subterminal bars; axillars and 
wing-lining chestnut; wings and tail black, the feathers edged with blue 
and tipped with white. Length, about 215; wing, 125; tail, 81; culmen 
from base, 21; bill from nostril, 14; tarsus, 27.5. This plumage is the 
one usually found in winter birds in the Philippines. “At the end of 
winter the white fringes and subterminal black bars on the blue parts 
of the plumage are entirely lost, and the marks on the chestnut parts 
are also removed by abrasion in great measure, but never entirely.” 
(Oates.) 
“The female much resembles the autumn plumage of the male, except 
that the blue of the upper parts is much duller and the whole of the 
under parts are pale whitish brown, suffused with pale buffish brown on

Richmond.
