As I admired this large sombre bird, which shared its display with Andean Cocks-of-the-Rock and Blond-crested Woodpeckers Celeus f!avescens), Assistant Director Ernest Roni, who was escorting me through the house, pointed with delight at a female Ringed Teal escorting a line of duck lings out of the undergrowth to the stream at the front ofthe exhibit. The Ringed Teal, which breeds in tropical Argentina and Paraguay, and ranges into Brazil, Bolivia, and Uruguay, is primarily a forest bird (Delacour, 1956;Johnsgard, 1978). It is frequently perched in trees and nests in tree-holes and the bulky stick nests of Monk Parrots (Delacour, Two Ringed Teal drakes, thefil'St oftheil' kind in EU1'Ope, keeping highly 1956; Johnsgard, 1978; and Todd, distinguished company atZoologischer Gm'ten Berlin in 1907, depicted 1979).

As the "ringed" pattern graph was prominently featured in of the male's head is often not ve~ r-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ obvious, I agree with zoo historian Marvin Jones that the German name "Red-shouldered Teal" is far more appropriate. It was to Germany that the first Ringed Teal were exported from South America, arriving at Zoolo gischer Garten Berlin, in the compar atively late year of 1907. The year is usually given as 1908, but the accom panying picture is dated a year earlier by avicultural historian HeinZ-Sigurd Raethel (1979). Berlin's first speci mens, regarded as treasured rarities in what was then the largest collec tion of birds in the world, were all males (Delacour 1956). Delacour (1956) further records that others shortly arrived in German private collections, the London Zoo, and the legendary aviaries of F.E. Blaauw at Gooilust, Holland. Though Blaauw shortly bred large numbers of Ringed Teal, the first success appears to have occurred in Germany, as Delacour (1956) notes that young birds were offered on Gerlnan price-lists in 1911. British successes soon followed; the great statesman, Lord Grey of Fallodon (Teddy Roosevelt's birding buddy), doing particularly well.
