RED-WHISKERED BULBUL IN FLORIDA: 1960-71 ALISON RAND CARLETON AND OSCAR T. OWRE THE suburbs about Kendall, I)ade County, Florida support an expanding population of the first bulbuls (Pycnonotidae) in the New World. Red-whiskered Bulbuls (Pycnonotus jocosus) escaped from captivity here in the summer of 1960 (Fisk 1966). Their successful invasion of southeastern Florida provided opportunity for the study of the biology of introduction and insight into the ecology of a rapidly changing region that comprises a large part of the only tropical portion of the continental United States. The Kendall bulbuls came from the eastern portion of the Indian peninsula and are assignable to the subspecies P. j. emeria (Linnaeus) (Banks and Laybourne 1968). This part of India and southeastern Florida are climatically somewhat similar. In the several decades preceding the release of the bulbuls, changes in the ecology of southeastern Florida made the region, in some ways, increasingly similar to the Indian habitat of P. jocosus (Owre 1973). Colonization by exotics is often facilitated in man-modified regions (Elton 1958). Changes in the ecology of southeastern Florida have probably been as rapid and as profound as any generated by man in the United States. The increase in human population, in 1970 ten times that of 1930 in the four southeastern counties (Bur. Census 1932, 1971), and the accompanying urban-suburban sprawl are spectacular. Natural ecological communities of the Atlantic coastal ridge are largely gone, while the flora of remaining open spaces is largely exotic. Sturrock and Menninger (1946) estimated the number of species of exotic trees and shrubs established in southeastern Florida at more than 1000. Aspects of this flora merit elaboration.
