Happy news! For the first time in 25 years, a baby orangutan was born at the National Zoo in Washington D.C. Zoo officials say they are”cautiously optimistic” that the baby boy will survive and thrive——or do well. His birth is important because he is part of a critically endangered species. Orangutans are listed as critically endangered, mostly because of habitat loss. Their population has dropped more than 50 percent over the past 60 years. Each and every birth of a critically endangered species is significant, but it is all the more exciting and this is a historic moment for the zoo.
