Driest in the center and wettest in the eastern pantanal savanna, the chaco experiences occasional frost throughout. About 409 avian species, including 22 that barely reach its borders, are resident or breed in the chaco. These number 218 nonpasserine birds, 100 suboscine passerines, including 52 tyrant flycatchers, 20 oscine passerines of Old World groups, and 71 New World nine-primaried oscines. Each species is treated taxonomically (based on a systematic reappraisal of each taxon), ecologically, and distributionally. There seem to be more superspecies in the chaco and in the tropics generally than in temperate North America. Most chaco species (252) are endemic in South America, but 28 percent reach Middle America, 12 percent attain North America, and 3 percent reach the Old World. A transatlantic distributional history is possible... |
