The Bronx Zoo opened on November 8th, 1899 with 843 animals (there are now over 4,000). Upon its 110th birthday, the Daily News lists off 110 other things you should know about the place (leaving out the time they caged a Congolese pygmy for a "Human Exhibit").
The Zoo says the perfect time to visit is in the fall (don't plan on a Thanksgiving trip, however, as that is one of the three days they are closed), noting that "The cool weather agrees with animals that have furry coats, insulating feathers, and hairy backs." And starting this month they're offering $5 carriage horse rides! (Ruh roh.) Check out some more old photos here.
