Bower's Shrike-thrushes are small shrike-thrushes.
Their morphology is
dimorphic, i.e.
males and
females
are slightly different.
Males
have a dark-grey head with light-grey chin and throat with light
grey striation. The upperparts are also dark-grey, with rufous
edge-lining on the wing feathers. The underparts, from the chest
downward to the undertail coverts, are cinnamon to rufous.
Males
also have a heavy black bill.
Females
have rufous lores and eye-rings. Their upperparts are slightly
less dark and the bill is also less dark and massive than the
males'.
The irises of both sexes are brown. The legs and feet are dark-grey.
Juvenile
birds resemble
females,
with more rufous on their upperparts and more streaking down the
front.
Immatures retain their rufous wing coverts, but otherwise resemble
females
more closely.
