A century ago, West Africa's giraffes numbered in the thousands, with their habitat spanning from Chad to Senegal's Atlantic Ocean coast.

The Denver Zoo has welcomed its fifth baby okapi, the first of the species to be delivered at the zoo since December 2007. The okapi, the only surviving species closely related to the giraffe, is native to the Ituri Forest in the Democratic Republic of Congo, where it is threatened by a long running civil war. The zoo announced Thursday the latest arrival, a female named Kalispell, was born June 27.

Officials at the Louisville Zoo in Kentucky said a baby giraffe born in February with a deformity has joined the rest of the herd on display after treatment. Candy McMahan, assistant mammal curator at the zoo, said Bakari, a Masai giraffe born Feb.

Researchers confirmed the discovery of an African animal so secretive it was once believed to be a mythical unicorn has been caught on camera in the wild.

One of the Philadelphia Zoo's most beloved animals is being remembered today as a "gentle and friendly favorite among keepers and visitors" after being euthanized last week, zoo officials said.
