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 huffish brown on 



* I use Forster's name for this rock thrush on the recommendation of Dr. C. W. 

 Richmond.
