My fellow-author of the present work, though English in name and origin
and now resident in London, is an Argentine citizen by birth. From his
early childhood he was an observer of bird-life in the province of
Buenos Ayres, and continued his investigations until he left the country
for England a few years ago. Besides the pampas he explored the woods
and marshes along the Plata, and the range of the Sierras from Cape
Corrientes on the Atlantic to the Azul and Tapalquen, and made an
expedition to the Rio Negro in 1871.
