(WASHINGTON) — There is a panda watch under way at the National Zoo in Washington, D.C.
Scientists say the female giant panda may be pregnant. She has been building a nest, is sensitive to noise and her hormone levels are high.
The zoo has closed part of the panda exhibit so she can have some privacy.
