This small Tyrant-bird is a summer visitor in the Plata district; it

is shy and solitary; frequents woods and plantations, and perpetually

utters, like the English Redstart, its sorrowful monotonous plaint, as

it flits about in the upper foliage of the trees.

The nest is placed in a bush or low tree, and built of various soft

materials compactly woven together, and the inside lined with feathers

or vegetable down. The eggs are four, pale cream-colour, with large,

well-defined spots of dark red.

The total length of this species is less than five inches. The

prevailing colour of the plumage is rufous brown on the upper, and

whitish brown on the under surface. Beneath the loose feathers of the

crown there is a concealed spot of orange-red.
