Adult summer plumage.--"In normal full summer plumage the forehead,
anterior part of crown, a broad supercilium, cheeks, ear-coverts,
and sides of the neck white; remainder of crown and nape, a streak
from the lores through the eye and over the ear-coverts, chin, throat,
and upper breast black; remainder of lower plumage white, shaded with
gray on the flanks; upper plumage gray, turning to black on the upper
tail-coverts; lesser wing-coverts gray; median coverts dark brown,
broadly tipped with white; greater coverts with the outer webs and
a considerable portion of the inner white; quills dark brown, edged
with white, the later secondaries very broadly so; the two outer pairs
of tail-feathers nearly entirely white, the others black." (Oates.)
Winter plumage.--A female, taken in Calayan Island in October,
1903, resembles the adult in summer as described above, but the chin
and middle of throat are white, the black patch of the chest being
crescentic in shape with its horns extending up the sides of the
throat. Iris brown; bill, legs, and nails black. Length, 200; wing,
90; tail, 92; culmen from base, 15; tarsus, 22.
Young.-- A female from Lubang Island, taken in November, 1902,
differs from the preceding specimen in having the entire top of
head and back drab-gray instead of black and ashy gray; the dark
line through eye drab-gray like the crown; the white forehead and
supercilium but faintly indicated by the white bases of the feathers.
The streak-eyed wagtail is of somewhat rare occurrence in the
Philippine Islands; it is easily distinguished by its black and white
under parts.
"A small flock of M. ocularis was observed in Palawan in December,
1891, and two specimens were obtained. They are both young birds in
first winter plumage. A male measures: Length, 178; wing, 90; tail,
97; culmen, 16.5; tarsus, 24; middle toe with claw, 20. A female,
length, 159; wing, 77; tail, 72; tarsus, 24; middle toe with claw,
20." (Bourns and Worcester MS.)
