For the first time, Bird House keepers at Smithsonian’s National Zoo and Conservation Biology Institute are celebrating the hatching of two critically endangered blue-billed curassows. The two female chicks are being cared for off-exhibit. The first chick, named Aluna, hatched Aug. 5. Her sister Lulo hatched Aug. 28. Aluna is the first offspring for 6-year-old mother, Jackie; the 16-year-old father, JB, previously sired chicks at another institution. Keepers report that the sisters are thriving and describe them as confident and curious.
