514. MIXORNIS CAGAYANENSIS Guillemard. 

 CAGAYAN SULTT TIT BABBLER. 



Mixornia cagayanensis GUILLEMARD, Proc. Zool. Soc. (1885), 419, pi. 25; 

 SHABPE, Hand-List (1903), 4, 53; MCGREGOR and WORCESTER, Hand- 

 List (1906), 82. 



Cagayan Sulu ( Guillemard) . 



Male. "Above grayish olive; the forehead grayish, with black shafts 

 to the feathers, the occipital region with a tinge of chesnut; feathers 

 round the eye and in the parotic region ashy ; throat and chin pure white, 

 broadly striped with black; breast pale yellow, also broadly striped, 

 shading off below into the yellowish olive-gray of the crissum and under 

 tail-coverts ; thighs with a slight reddish tint ; under wing-coverts white ; 

 wings chestnut; tail brown with traces of dark barring. Iris pale 

 yellow; bill and feet lead-colored. Length, about 145: wing, 64; tail, 

 60 ; bill from gape, 18 ; tarsus, 20. 



"This species, which was common in low bushes in the 'more open 

 situations in the island, is at once distinguishable from M. bornensis by 

 the upper surface being of an ashy olive-brown instead of chestnut. It 

 has a loud note of alarm, is very restless in its movements, and apparently 

 rarely flies far off the ground." (Guillemard.) 



Genus MACRONOUS Jardine and Selby, 1835. 



Rictal bristles about as long as bill from nostril; nasal opening oval 

 and not protected by a flap; culmen from base less than tarsus; long 

 feathers of the back reaching to or beyond the tips of tail-coverts, their 

 shafts stiff and usually white ; feathers on sides of body long, decomposed, 

 and hair-like; most of the plumage loose and decomposed. Macronoiis 

 resembles Mixornis in its long dorsal feathers, but differs from the latter 

 in having the shafts of these feathers thick and stiff. Zosterornis differs 

 from both of these genera in having shorter dorsal plumes and in having 

 a flap above the nasal opening.
