Particularly was this the case with those species, mainly shore birds, that pass south into the southern portion of the South American Continent. To gather first hand information on the questions involved the Biological Survey, United States Department of Agriculture, in May, 1920, dispatched the writer to Argentina with instructions to carry on the desired observations. During the extended period of field work incident to such a task there was abundant Opportunity to make representative collections of native birds and to record many points of interest concerning their distribution and habits. Since observation of shore birds was the main object in mind, travel was restricted largely to the level sections where suitable shores and marshes were available, so that collections were made in the main in the lowlands. The area covered extended from north ern Paraguay south to northern Patagonia, and from the eastern border of Uruguay west to the foothills of the Andes in Mendoza, and included a limited section near Valparaiso, Chile. Points for work were chosen carefully to allow comprehensive survey of as large an area as practicable. Studies of the specimens secured to gether with field observations, where pertinent, are presented here with in as much detail as is warranted. For assistance while in South America, thanks are due especially to Dr. Roberto Dabbene of the Museo Nacional in Buenos Aires.

DOWNLOAD EBOOK →This is the first comprehensive guide to these closely related families. The book covers all 75 wrens, 34 thrashers and 5 dippers, almost all of which are New World species. The wrens (Troglodytidae) in particular display great diversity, occupying almost every kind of habitat in the Americas. The family probably originates in Central America where the greatest number of species is to be found. The thrashers (Mimidae) include the mockingbirds, catbirds and tremblers. The dippers (Cinclidae) are river specialists although, unusually, they exhibit no obvious features for an aquatic existence.
