_Description._--Above dark brown; head black, with a central and

two lateral longitudinal bands of buffy white; wings ashy blackish,

spotted with buffy white and barred with black; coverts with large

oval spots of clear white: beneath, throat and breast dark brownish,

with a conspicuous white neck-collar on each side; belly white,

flanks tinged with buffy; bill greenish, reddish at tip; feet

flesh-colour: whole length 8·0 inches, wing 4·1, tail 2·0. _Female_

similar, but slightly larger and more brightly coloured.

_Hab._ Southern parts of South America, from Peru to Patagonia.

In the Argentine provinces this bird is called _Dormilon_ (Sleepy-head),

in allusion to its dull habits, which are like those of a nocturnal

species. It passes the daylight hours concealed in dense reed-beds,

rising only when almost trodden on; the flight is feeble and erratic,

the rapid wing-flutterings alternating with intervals of gliding, and

after going a short distance the bird drops again like a Rail into

the rushes. From its behaviour on the ground, also in flying, when it

appears dazed with the light, I have no doubt that it is altogether

nocturnal or crepuscular in its habits. It is solitary and resident, and

may be met with in small numbers in every marsh or stream in the Plata

district, where its favourite reed-beds afford it cover. It appears to

have no cry or note of any kind, for even when frightened from its nest

and when the eggs are on the point of hatching it utters no sound. The

eggs never exceed two in number and are placed on the wet ground, often

without any lining, among the close grass and herbage near the water.

They are oblong and bluntly pointed at the smaller end, and have a white

ground-colour, but so densely marked and blotched with black that in

some cases they appear to be almost wholly of that colour, or like black

eggs flecked with white.
