This small and pretty Tyrant-bird is quite common in the woods along
the Plata, and is also seen a great deal in orchards and groves in the
cultivated districts. In Buenos Ayres it is a summer visitor, appearing
there in October, and is a shy, solitary bird, which catches insects on
the wing, and rarely visits the ground.
The nest is placed in a tree, ill-concealed, and very shallow: it
is built of fine sticks, and lined with fine grass, horse-hair, and
feathers. The eggs are four, pointed, pale cream-colour, with large dark
red spots, chiefly at the larger end.
The only language of this species is a very low plaintive whistle,
uttered as a faint protest when the nest is approached.
The upper plumage is olive-green; the entire under surface and a stripe
on the side of the head pure yellow; wing and tail-quills dark. Total
length 6-1/4 inches.
