Puebloan Agriculture and its Impact on the Migratory Behavior of Birds

Abstract

Towards the end of the thirteenth century, the Albuquerque Basin of New Mexico saw a significant increase in population from Puebloan peoples migrating into the valley. By the time of the Coronado expedition in 1541–1542, this area contained 12 large pueblos along the roughly 55 km long by 5 km wide Rio Grande floodplain, resulting in one of the densest concentrations of pueblos and agricultural fields in the Eastern Pueblo region. Zooarchaeological analyses of Classic Period faunal assemblages have yielded an abundance and diversity of wild bird remains with an emphasis towards migratory birds that reside in the region during the winter. These avifauna are almost entirely absent from the archaeological record of the preceding Developmental Period. This paper argues that changes in Puebloan farming practices between the two periods had a direct effect on shifting the traditional wintering grounds of these migratory birds northwards into the Albuquerque Basin.
