ground, watching for insects. On the bare ground they run about with
wonderful swiftness, and are able to overtake and capture flying insects
without rising. The male and female invariably hunt together, and at
intervals fly to some favourite perch to indulge in a duet composed of
loud, rapid, shrill notes, somewhat metallic in sound. Though able to
fly swiftly when in pursuit of a passing hawk or other bird, at other
times their flight is strangely slow; the round body, short blunt wings
and tail giving the bird a somewhat curious appearance as it progresses
laboriously through the air. I have frequently seen them make the most
unprovoked assaults on birds of an inoffensive kind; possibly they are
in these attacks moved by a playful rather than by a vindictive spirit.
I once saw one drop like a stone from a height of fifty yards on to a
Pigeon perched on a leafless tree. The Pigeon fell as if shot to the
earth; the Tyrant-bird then released his hold; the Pigeon rushed away
terrified through the trees, while its persecutor rose high up in the
air and resumed its journey.
I have elsewhere spoken of the wars waged by this bird against other
species, all seeking to gain possession of the large nest of _Anumbius
acuticaudatus_. A hole in the trunk of a tree is also a favourite
breeding-place. The nest is neatly built of slender twigs and leaves,
and lined with horse-hair. The eggs are slightly oval, and densely
marked with dark brown spots or stripes on a white or brownish-white
ground.
133. MUSCISAXICOLA MACLOVIANA (Garn.). (CHIN-SPOTTED TYRANT.)
+Muscisaxicola mentalis+, _Hudson, P. Z. S._ 1872, p. 541 (Rio
Negro); _Scl. et Salv. Nomencl._ p. 44.
_Description._--Above cinereous, lores blackish, cap brown;
tail-coverts and tail black, outer margins of outer tail-feather
white; below pale cinereous, passing into white on lower belly,
crissum, and under wing-coverts; chin-spot brown: bill and feet
black: whole length 6路1 inches, wing 4路1, tail 2路6. _Female_
similar, but chin-spot not so well marked.
_Hab._ Peru, Bolivia, Chili, Patagonia, and Falkland Islands.
This South-Patagonian species is one of a Chilian group of Tyrant-birds
which resemble in their habits the _Saxicol忙_ of Europe. The plumage is
generally grey, with more or less rufous colour on the crown; they have
long legs, and run swiftly on the ground, frequent open sterile
situations, and perch only occasionally on trees.
The present bird is about seven inches long; the upper parts are dull
grey, except the crown, which is dark chestnut; under surface light
grey, and tail nearly black. In the month of June I met with these birds
on the Rio Negro, on their arrival there from the south. They went in
flocks of a dozen or twenty birds; they had a swift easy flight, were
shy and restless in their manner, and uttered low plaintive whistling
notes. When a flock alights on the ground the birds all instantly
scatter, running rapidly about in all directions over the bare ground.
Occasionally one was seen to perch on some slight elevation, and dart
like a Flycatcher after passing insects.
Darwin saw this bird as far north on the Atlantic coast as Bahia Blanca.
He also found it at Tierra del Fuego, where it lives entirely on the
sea-beaches; and in the sterile upper valleys of the Chilian Andes, at a
height of ten thousand feet, where the last traces of vegetation occur
and where no other bird lives.
134. MUSCISAXICOLA RUFIVERTEX, d'Orb. et Lafr. (RED-TOPPED TYRANT.)
+Ptyonura rufivertex+, _Burm. La-Plata Reise_, ii. p. 461 (Mendoza).
_Description._--Above clear cinereous; lores and short
superciliaries whitish; well-defined nape-patch bright rufous; wings
brownish; upper tail-coverts and tail black, outer margin of outer
rectrix white: below clear cinereous white, brighter on lower belly,
crissum, and under wing-coverts; bill and feet black: whole length
6路5 inches, wing 4路0, tail 2路8. _Female_ similar.
_Hab._ Peru, Bolivia, Chili, and Western Argentina.
MUSCISAXICOLA MACULIROSTRIS, d'Orb. et Lafr.
(SPOT-BILLED TYRANT.)
+Muscisaxicola maculirostris+, _Scl. et Salv. Nomencl._ p. 44;
_Durnford, Ibis_, 1878, p. 395 (Centr. Patagonia). +Ptyonura
maculirostris+, _Burm. La-Plata Reise_, ii. p. 462 (Mendoza).
_Description._--Above greyish brown, lores and slight superciliaries
whitish; tail-coverts and tail black, the outer web of the outer
rectrix white; below pale greyish white, whiter on the belly and
crissum; bill black, with the base of the lower mandible yellowish;
feet black: whole length 5路5 inches, wing 3路4, tail 2路4. _Female_
similar.
_Hab._ Chili, Patagonia, Bolivia, Peru, and Western Ecuador.
Prof. Burmeister met with this species near Mendoza, in the mouths of
the large torrents above the city. Durnford found it near the river
Sengalen in Central Patagonia in December 1877.
136. CENTRITES NIGER (Bodd.). (RED-BACKED TYRANT.)
+Centrites niger+, _Burm. La-Plata Reise_, ii. p. 458; _Scl. et Salv.
Nomencl._ p. 44; _Durnford, Ibis_, 1878, p. 395 (Chupat); _White,
Z. S._ 1882, p. 604 (Buenos Ayres); _D枚ring, Exp. al RioNegro, Zool._ p. 42 (R. Colorado); _Barrows, Bull. Nutt. Orn.
Cl._ viii. p. 142 (Entrerios, Pampas).
_Description._--Above and below deep black: whole of back except
the rump and scapularies chestnut; bill and feet black; under
wing-coverts and wings below black: whole length 5路0 inches, wing
2路8, tail 1路9. _Female_ above brown, back fulvous red; tail black;
below ashy brown.
_Hab._ Patagonia, Chili, and Argentina.
The little Red-backed Tyrant comes nearest to _Muscisaxicola mentalis_
in habits, but does not perch on bushes and trees, and is less
gregarious than that bird. It is the smallest of all those varied
members of the _Tyrannine_ family which have abandoned forests and
marshes and the pursuit of insects on the wing, to live on the wintry
uplands of Patagonia, and on the sterile plains bordering on the Andes.
The male is only five and a quarter inches long. The entire plumage of
the male is intensely black, except the back, which is bright chestnut.
The inside of the mouth and tongue are vivid orange-yellow. The chestnut
colour on the female is pale, the rest of the plumage grey, except the
quills, which are dark.
Its summer home is in the southern portion of Patagonia, but its
nesting-habits are not known. In March it migrates north, and is very
common everywhere on the pampas throughout the winter. They arrive in
small parties of three or four, or in little loose flocks of about a
dozen individuals, travelling with a swift low flight. Males, females,
and young, grey like the last, arrive together; shortly after arriving
the young males become mottled with black, and before leaving acquire
the adult plumage. They appear to leave in spring all together, but from
a note by Durnford it would appear that the males travel in advance of
the females. He says:--"Males of this species were common at Chupat
throughout September and during the first few days of October. On the
5th of the latter month I observed the first females, which gradually
increased in number."
The Little Red-backs inhabit open unsheltered plains, and have so great
a predilection for bare ground on which they can run freely about, that
on their arrival on the pampas, where the earth is thickly carpeted with
grass, they are seen attaching themselves to roads, sheep-pens, borders
of streams, vizcacha villages, and similar places. They are exceedingly
restless, running swiftly over the ground, occasionally darting into the
air in pursuit of small flies, and all the flock so scattered that there
will be a dozen yards between every two birds. Mr. Barrows describes
their lively habits very well:--"I think this is one of the most
restless birds I ever saw. You cannot depend upon him to be in the same
place two consecutive half-seconds. He runs like a Sanderling, and
whenever he keeps his feet still by accident, his wings are flirted
in a way that shows his anxiety to be off. Several are usually found
together, and sometimes a loose flock of a hundred or more is seen. They
are very strong on the wing, sometimes mounting rapidly for several
hundred feet, if suddenly startled, and after a few moments spent in
circling like a Snipe, they drop again almost as suddenly as a shot, and
as if from the very clouds."
137. PLATYRHYNCHUS MYSTACEUS (Vieill.). (BROAD-BILLED TYRANT.)
+Platyrhynchus mystaceus+, _Scl. et Salv. Nomencl._ p. 44; _White, P.
S._ 1882, p. 605 (Misiones).
_Description._--Above olive, darker on the head; coronal patch
bright yellow; lores, eye-region, and ear-coverts pale yellowish;
mystacal stripe blackish; wings and tail blackish edged with
olive-brown; below clear fulvous, much whiter on the throat; upper
mandible blackish, lower whitish; feet pale yellowish: whole length
3路3 inches, wing 2路1, tail 1路1. _Female_ similar, but no coronal
patch.
_Hab._ Guiana, Brazil, Paraguay, and Northern La Plata.
A single example of this species was obtained by White in the forest
near San Javier, Misiones.
