Abstract
Jamaica (4411 square miles) in the West Indies is the smallest island in the Western Hemisphere on which a bird species is known to have differentiated into taxonomically distinct populations (Bond 1956:95). One race T. p. scitulus of the endemic Jamaican Hummingbird Trochilus polytmus (L.) is confined to the extreme eastern end of the island, while the other, T. p. polytmus, occurs widely over the rest of the island. Here, we examine the geographical relationships of these two forms with particular emphasis on the zones of contact. Our study is based on the examination of museum specimens in the collections of the Museum of Comparative Zoology (MCZ), American Museum of Natural History (AMNH), Academy of Natural Sciences of Philadelphia (ANSP), U.S. National Museum (USNM), the Institute of Jamaica in Kingston (JI), and on the results of field studies in eastern Jamaica in January 1971.
