a sheltering hedge of thorn, and may generally be found in 
the same place from day to day, coming out about dusk in 
quest of moths and other insects.

Hitherto I have obtained no specimen of this bird, though 
I have constantly observed it in the spring and autumn. It 
lives on the ground, generally in damp situations and where 
the grass is long and thick enough to afford some slight 
cover. I have always observed it in parties of four or five 
individuals. Its flight is noiseless, and performed by jerky 
erratic movements; when on the ground it always squats in¬ 
stead of standing.

Resident, and common to the north of Buenos Ayres and 
on the banks of the Parana to Baradero.

Not uncommon about the creeks and streams at the mouth 
of the Parana. Common at Baradero in April.

A few remain with us all the winter; but the majority leave 
after the breeding-time. They have two broods in the season. 
Their usual note is a succession of harsh screams ; but they 
also have a rather musical note, which is uttered in two keys, 
and is something like the Curlew's note at home. Their food 
consists of snails, slugs, bits of meat or offal—in fact, almost 
any thing. In some of their habits and manner of flight they 
resemble our common Magpie at home, never flying far with¬ 
out alighting, and generally keeping together in small parties. 
During cold and cloudy weather in winter they are rarely 
seen; but a bright warm day seems to endue them with fresh 
life and activity.
