  • Languages of the Middle Andes in Areal-Typological Perspective: Emphasis on Quechuan and Aymaran
    Languages of the Middle Andes in areal-typological perspective: Emphasis on Quechuan and Aymaran Willem F.H. Adelaar 1. Introduction1 Among the indigenous languages of the Andean region of Ecuador, Peru, Bolivia, northern Chile and northern Argentina, Quechuan and Aymaran have traditionally occupied a dominant position. Both Quechuan and Aymaran are language families of several million speakers each. Quechuan consists of a conglomerate of geo- graphically defined varieties, traditionally referred to as Quechua “dialects”, not- withstanding the fact that mutual intelligibility is often lacking. Present-day Ayma- ran consists of two distinct languages that are not normally referred to as “dialects”. The absence of a demonstrable genetic relationship between the Quechuan and Aymaran language families, accompanied by a lack of recognizable external gen- etic connections, suggests a long period of independent development, which may hark back to a period of incipient subsistence agriculture roughly dated between 8000 and 5000 BP (Torero 2002: 123–124), long before the Andean civilization at- tained its highest stages of complexity. Quechuan and Aymaran feature a great amount of detailed structural, phono- logical and lexical similarities and thus exemplify one of the most intriguing and intense cases of language contact to be found in the entire world. Often treated as a product of long-term convergence, the similarities between the Quechuan and Ay- maran families can best be understood as the result of an intense period of social and cultural intertwinement, which must have pre-dated the stage of the proto-lan- guages and was in turn followed by a protracted process of incidental and locally confined diffusion.

The project was carried out in villages of the six southern provinces of the department of Cajamarca. The comparison was performed tak- ing into account two parameters: technical uniformity or diversity in ‘plain’ pottery and weaving, and presence or absence of lexical items of indigenous origin – both Quechua and pre-Quechua – in the vocabulary of both handicraft activities. Pottery and weaving differ in the two observed domains. On the one hand, pottery shows more technical diver- sity than weaving: two different manufacturing techniques, with variants, were identied in pottery. Weaving with the backstrap loom ( telar de cintura ) is the only manufacturing tech- nique of probable precolonial origin in the area, and demonstrates remarkable uniformity in Southern Cajamarca, considering the toolkit and the basic sequence of ‘plain’ weaving.

  • A Woolly Monkey Rediscovered in Peru Russell A
    '* A Woolly Monkey Rediscovered in Peru Russell A. Mittermeier, Hernando de Macedo Ruiz, and Anthony Luscombe The Peruvian yellow-tailed woolly monkey, last seen by scientists in 1926 and feared extinct, was rediscovered by the authors in the area of the lower Andes where it was last seen. They were able to bring back a live juvenile that was being kept as a pet, and also four skins and three skulls which they got from a hunter who had shot the animals for meat. The authors urge the need to create a reserve for this rare endemic monkey in Peru and plan further exploratory trips to decide the best area. The two species of large prehensile-tailed woolly monkeys are found primarily in the Amazon basin. Lagothrix lagothricha is divided into four subspecies, all widely distributed in the rain forests of Brazil, Colombia, Peru, Ecuador and Bolivia, all commonly exhibited in zoos, and all, until recently, frequently sold as pets. L. ftavicauda, the Peruvian yellow-tailed woolly monkey, how- ever, is restricted to a small area in Peru and occurs only in finger-like pro- jections of Amazon forest into the Andes. The rarest of New World monkeys, until last year it was known only from five museum specimens, the last collected in 1926. Scientists thought it might already be extinct. Early in 1974 we organised a brief expedition to the area where the last known specimens had been collected, and were able to obtain proof, in the form of four skins, three skulls and the first living specimen ever seen by members of the scientific community, that the monkey still existed.

Peruvian cartography in the nineteenth century was very rich and fulfilled the geographic know- ledge demanded by the new Republic of Peru. In effect, the country of more than 1,000,000 km2 needed to show the physical environment and to locate the distribution of its natural resources. It was the time when cartography was valued as an element of empowerment and land control, especially when the political borders were rather unstable (G. Prieto 2018). Then, it was timely the publication of Atlas Geográfico del Perú (Geo- graphic Atlas of Peru) by Mariano Felipe Paz Soldán, a prominent Peruvian lawyer and geographer. Author’s purpose is to comment on the new edition of the Mariano Felipe Paz Soldán Atlas Geográfico del Perú, published in Lima in 2012. Keywords: Peruvian maps in the 19th century, Paz Soldán Atlas 1. Introduction according to R. Porras-Barrenechea (1963, p. 411) is “the best cartographic synthesis of The first cartographic information regarding that time”. Peru appeared during colonial times.

    1ovitatesMhimeuicanJiuseum PUBLISHED BY THE AMERICAN MUSEUM OF NATURAL HISTORY CENTRAL PARK WEST AT 79TH STREET, NEW YORK 24, N.Y. NUMBER 2 028 MAY 8, 196I Birds of the Western Slope of the Andes of Peru1 BY MARIA KOEPCKE2 INTRODUCTION During the ecological and zoogeographical studies that I undertook with my husband, H.-W. Koepcke, in the course of nine years on the western side ofthe Peruvian Andes, I observed that a considerable num- ber of birds have a more extensive distribution than had been known heretofore. It had not been perceived that several life zones ofnorthwest- ern Peru and western Ecuador, with their special biotopes, extend along the western slope of the Andes to middle Peru and beyond. The most interesting findings seem to be that the humid division of the temperate zone described by Chapman (1926) for Ecuador and northwestern Peru extends at least to middle Peru, split into a chain of "insular woods" (M. Koepcke, 1954, 1957, 1958; H.-W. Koepcke, 1958, and MS), and, moreover, the fact that we find in middle Peru, in the lower part of the western Andean slope, the southernmost patches of forest composed of trees which shed their leaves during the dry season. I have included a few observations on birds of the ocean shores and on migratory birds. I found further novelties in relation to distribution during a revision of Peruvian birds in the American Museum of Natural History in New 'Taxonomical and faunal bases for the ecological-zoogeographical studies of H.-W. and M.

Breeding of the Green-bellied Hummingbird.--On 21 February 1970 near Moco Moco creek in the Kanuka Mountains of southern Guyana at approximately 85 m elevation we found a nest of the Green-bellied Hummingbird (Amazilia viridigaster), which has not previously been described. The nest contained two half-fledged young, and we had good views of the parent returning to feed the nestlings. The nest was in a small tree growing from a rocky cleft beside a waterfall, and was fixed by cobwebs to two fine twigs near the end of a side branch, 3 m above the ground. After the young had left we collected the nest. It is a typical hummingbird cup nest with an outer layer of moss encasedby cobwebs,some lichen decorations, and a lining of a thick layer of tawny-colored vegetable down. Its dimensions are: internal diameter of cup 30 ram, depth of cup 14 ram, total depth of nest During our 3 months' residence at Moco Moco creek (January-April 1970), we saw Green-bellied Hummingbirds often. Two were trapped, weighed (4.1 g and 3.9 g), and color-photographed. Identification was confirnled by comparison of the photographs with museum specimens.
