from Europe and Africa as in our wood warblers traveling from 

 Canada and the United States to South America and back. One of the 

 fundamental differences in migration patterns of the Northern and 

 Southern Hemispheres is that no land species nesting in the South 

 Temperate Zone migrates into the North Temperate Zone, but a few 

 seabirds, such as the sooty shearwater, Wilson's storm-petrel, and 

 others, migrate north across the Equator over the vast ocean 

 expanses after nesting in the South.
