Antarctic birds are breeding later
As global temperatures rise, Arctic birds are breeding earlier than they did in previous decades. However, the reverse is true in Antarctica, new research shows.
“In the Arctic, spring basically comes earlier, and most species [of migratory birds] respond by arriving and laying eggs sooner,” says Christophe Barbraud, an ornithologist at the National Center for Scientific Research in Villiers en Bois, France. But there have been few studies of the phenomenon in the southern hemisphere.
