This large flycatcher, though found on the pampas, was more
common at the border of forests, along fence rows, or in open
brush. It was especially partial to water and was observed fre-
quently perched on limbs or rushes that overhung small streams
or marshes. It was observed often in parks in cities where tree
growth was extensive, and is one of the first of the native birds
to attract the attention of the traveler, its presence constantly ad-
vertised by its querulous notes. The birds usually watched for
prey from some open post, and on occasion, from their intent gaze
at the water, I suspected that they were on the lookout for small
fishes. Occasionally they hovered in the air like kingfishers or small
hawks, with the body suspended at an angle of 45° and rapidly
beating wings. They were solitary save during the breeding sea-
son, when they congregated in pairs.
Their mating display, observed occasionally, was peculiar. The
individual giving it, stood bolt erect with the neck perpendicular,
threw the point of the bill down and exposed the flaring, colored
crest directly in front, while it shook the wings rapidly and made
a loud cracking sound with its bill. Nest building began in Oc-
tober, and during November their large nests, often with crudely
formed roofs, were seen on several occasions. Domed nests, common
among pampas inhabiting birds, apparently give protection from
predatory animals and shelter from the heavy storms of spring.
A young bird, recently from the nest, was shot at San Vicente,
Uruguay, January 25.
Local names for this well-known species are given almost universally
in imitation of its notes, as witness hien-te-veo in Spanish, pH-
o-giie in Guarani, and heht aow pah in Anguete.

The present species, seen only in Paraguay, in the region near
Puerto Pinasco, was migratory, and did not appear during spring
until September 20, when a male was shot near Kilometer 80, Another
was recorded near the same point on September 21, one near
