This photo released by the Lincoln Children's Zoo, shows Milla, a Matschie's tree kangaroo, on Tuesday, Jan. 6, 2009 in Lincoln, Neb. The Lincoln Children's Zoo is celebrating its first set of Matschie's tree kangaroo twins and an official who tracks numbers of the extremely rare species says it's the first documented case in North America among records that go back to the 1970s. The twins born last month to Milla and her mate Noru, brought in from the Toronto Zoo, make up half of the four documented Matschie's tree kangaroo births in 2008. The twins are in her pouch.
