Roger Williams Park Zoo has a "little" reason to celebrate Mother's Day.
The zoo announced Thursday the birth of a Matschie's tree kangaroo. The baby was born in October, but just recently started poking its head out of the mother's pouch.
It was the first tree roo born at the Providence zoo in over 20 years.
Tree kangaroos are an endangered species. There are fewer than 2,500 of them in the wild. The Matschie's tree kangaroo is indigenous to the rainforests of Papua New Guinea.
The zoo said there are only 53 tree roos in the U.S. living in captivity, and seven in international facilities.
The pregnancy pushed back the zoo's plans to build a new tree roo exhibit. Construction will begin in late June with a projected opening for the new exhibit in early fall.
Until the exhibit is completed, images of the baby roo's development in the pouch will be displayed in the Australasia building, Roger Williams Park Zoo said.
