Luzon (Heriot, Whitehead).
"Adult male.--Like the male of S. pallidipes, but the sides and
flanks are fawn-colored instead of pure white. Length, 152; culmen,
18; wing, 79; tail, 63; tarsus, 22.
"Adult female.--Even more different from the female of S. pallidipes:
the lores are rust-colored instead of white, and a short superciliary
band of the same color reaches as far as the eye, above this there
is a line of pale blue feathers, confluent across the forehead;
the basal part of the outer webs of the tail-feathers washed with
pale blue instead of reddish chestnut. Sides of the face dark brown,
shading gradually into the rust-colored throat, whereas in the female
of S. pallidipes the sides of the head are gray, and sharply defined
from the bright rust-colored throat. Length, 134; culmen, 16; wing,
74; tail, 55; tarsus, 18." (Grant.)
I have not seen the description of Cyornis herioti so have quoted
Grant's description of Siphia enganensis which is the same species. It
is evident that we have here a type differing from all the other
Philippine species of the genus. The male may be recognized by the
blue throat and breast. Heriot's flycatcher is either very rare,
or is confined to northern Luzon where it may prove to be abundant.
