The National Zoo initiates a "birth watch" on Giant Panda Ling-Ling. The watch, which was conducted by 95 Friends of the National Zoo volunteers working three hour shifts, day and night. The watch is ended at 7 a.m. on December 31, 1985, after scientists reviewing hormonal and behavioral data from other Panda pregnancies determined that a birth this season would be unlikely. Ling-Ling and the male panda, Hsing-Hsing, bred over a three-day period in late June and early July.
