This sort of biozone mixing can create a tremendous richness of species. Each of these habitats attracts its own group of species. I mentioned last week the Jamaican Nettletree, whose tiny fruit was attracting all kinds of species — even some I thought did not eat fruit or seeds. This one was a true lifer for me.

Trinidad is the northern limit of the range of the Red-breasted Blackbird , though it is unclear if the occasional birds that show up in Tobago are wanderers from Trinidad or northern South America or are breeding there. You can also find Red-breasted Blackbirds in Costa Rica and Panama and south to Peru and Brazil.

It actually makes a lot of sense, the geographic features of the isthmus between North America (including Mexico, because Mexico is part of North America) and South America cut across political lines, as do birds. In addition, 67 species are listed in a chapter entitled “Marginal, Dubious, and Hypothetical Species.”
