during four months in every year."

Of a tyrant-bird (_Pitangus Bolivianus_) Hudson writes
(_Argentine Ornithology_, vol. i, p. 148): "Though the male and
female are greatly attached, they do not go afield to hunt in
company, but separate to meet again at intervals during the day.
One of a couple (say, the female) returns to the trees where they

anxious at the delay of her consort, utters a very long, clear
call-note. He is perhaps a quarter of a mile away, watching for a
frog beside a pool, or beating over a thistle-bed, but he hears
the note and presently responds with one of equal power. Then,
perhaps, for half an hour, at intervals of half a minute, the
birds answer each other, though the powerful call of the one must
interfere with his hunting. At length he returns; then the two
birds, perched close together, with their yellow bosoms almost
touching, crests elevated, and beating the branch with their
wings, scream their loudest notes in concert--a confused jubilant
noise that rings through the whole plantation. Their joy at
meeting is patent, and their action corresponds to the warm
embrace of a loving human couple."

Of the red-breasted marsh-bird (_Leistes superciliaris_) Hudson
(_Argentine Ornithology_, vol. i, p. 100) writes: "These birds
are migratory, and appear everywhere in the eastern part of the
Argentine country early in October, arriving singly, after which
each male takes up a position in a field or open space abounding
with coarse grass and herbage, where he spends most of his time
perched on the summit of a tall stalk or weed, his glowing
