and nails light horn-blue. Whitehead gives the iris as “dark brown.” 
Length, including rackets, 305 to 317; two males measure, wing, 164 to 
166; tail, without rackets, 84 to 85; culmen from cere, 20 to 21; tarsus, 
15 to 16. 
Female.—Much like male but red and blue of head and face replaced 
by dark green ; a slight trace of blue on forehead and around eyes. Colors 
of soft parts as in the male. “Differs from the female of P. verticalis 
in having the head dull grass-green, the forehead, lores, sides of the crown, 
and feathers round the eyes being washed with blue. The under parts 
are like those of the male and never yellow-green as in the Sibutu female.” 
(Grant.) One female measures, wing, 158; tail without rackets, 83; 
culmen from cere, 20; tarsus, 17. 
Young.—Immature birds of each sex resemble the adult female. 
The mountain racket-tailed parrakeet was discovered by Whitehead in 
the mountains of Abra and Lepanto Provinces. At San Jose a live bird 
was purchased. The natives said it “had been snared in their maize-fields 
and that it was common enough when the cereal was ripe.” We collected 
a number of specimens in Benguet Province where it was not uncommon 
though somewhat difficult to secure; the species is well known to the 
Igorot by the name “u-lis.” It is improbable that this beautiful parrot 
occurs below the pine belt but with our meager knowledge of the vertical 
distribution of birds in the Philippines it is better to follow this statement 
with a large interrogation mark. This species is very noisy and does not 
differ in habits from lowland members of the genus.

Adult.—‘Very much like P. discurus, from which it differs in being larger and 
in the greater extension of the blue color on the crown, where it begins from the 
anterior edge of the forehead and extends to the occiput; also lores bluish green; 
on the nape and upper part of the back there is a very distinct olive patch, of the 
same color as the under parts. Length, 343; wing, 163; central tail-feathers, 
165; lateral tail-feathers, 76; bill, 23; tarsus, 17.” (Salvadori.)
