Birds and Birding's Guide to:Watching THE RHEASThe Long-billed RheaThe Long-billed Rhea (R. macrorhyncha), a bird similar in size and habits to the one just described, is found only in northeastern Brazil. It is browner in color and has the crown darker and the bill longer. It must be quite rare. The smallest of the Rheas is known as Darwin's Rhea (R. darwini), the first specimen having been obtained by him while on the celebrated voyage of the Beagle. It is only thirty-six inches in length and is found in Patagonia, mainly south of the Rio Negro.” When pursued it frequently attempts to elude the sight by suddenly squatting down among the bushes, which have a gray foliage, to which the color of its plumage closely assimilates.”It has much the same habit of holding up the wings when running as the Common Rhea, but usually it runs with its neck stretched forward, thus making it appear even lower than it really is. The nests are similar to those of the other species, each often containing 50 or more eggs. The eggs when first laid are a deep, rich green; this fades to a yellowish, then a stone blue, and finally almost white. Many waste eggs are found at a distance from the nest.
