A rare waddled crane chick was born at the Smithsonian’s National Zoo on March 30, the first of its kind in the zoo’s 118-year history.

The egg hatched after 33 days of incubation by two adult waddled cranes, according to a news release from the zoo. The Waddled Crane Species Survival Program selected the parents. Zoo staffers did not check on the egg during incubation so they would not disturb the expecting parents.

The population of waddled cranes has decreased with the destruction of their natural habitat, the wetlands of south-central Africa.

The crane chick’s gender is still unknown, and zoo staff members are awaiting the results of blood tests to verify it, according to the press release.

The young waddled crane lives at the zoo’s outdoor birdhouse with its parents and other species of cranes.
