“…The majority of biological invaders in recent centuries have travelled through the conscious or unconscious assistance of humans, although there have been a few notable exceptions (e.g. cattle egret, Bubulcus ibis Linnaeus, Handtke & Mauersberger, 1977). In addition, human presence commonly alters disturbance patterns, which may favour the expansion and persistence of exotics (Dukes & Mooney, 1999).…”

Most previous attempts to model the geographical range expansion of an invading species assume random dispersal of organisms through a homogeneous environment. These models result in a series of uniformly increasing circles radiating out from the centre of origin over time. Although these models often give reasonable fits to available data, they do not typically include mechanisms of dispersal. Alternatively, models that include assumptions of non‐random dispersal and a heterogeneous environment inevitably result in an anisotropic or jagged invasion front. This front will include propagules of pioneer individuals for the expanding species. Existing data from biological invasions reveal that the spatial structure of an invading species usually exhibits these propagules. Using population data gathered from the past century, we investigated the propagules of two North American invading bird species: the European starling (Sturnus vulgaris Linnaeus), and the house finch (Carpodacus mexicanus Müller), and found a correlation between propagule location and habitat quality. These results suggest that dispersing individuals seek out favourable habitat and remain there, thus introducing a possible mechanism for explaining non‐uniform dispersal during invasions. When combined with results from other studies, our results suggest that propagules provide starting points for future population expansion of an invading species.

“…In 1950, this egret successfully colonized parts of North and South America after a spectacular transatlantic crossing from Africa (for reviews see Handtke & Mauersberger 1977, Franchimont 1986aand Arendt 1988. Stragglers coming from Southeast Asia successfully invaded Australia in 1954 and many thousands pairs now breed there (McKilligan 1985).…”

In Europe and the Mediterranean Basin, where the natural environment has been dramatically altered by man, many species have vanished or became endangered whereas others have been able to expand their breeding range. This chapter deals only with a sample of some expanding species, most of them concern westward oriented expansions but also some northward expansions by Mediterranean and desertic species. Each of these range expansions reflects more a combination of several factors than the influence of a single factor. Species able to live in mostly open and eutrophic habitats shaped by man and/or in close contact with man seem to be favoured. Thus, the evergrowing impact of human activities now plays a significant role in recent bird invasions.
