Monkeys at Moscow Zoo.

Renovations in honour of the zoo's 150th anniversary are ongoing, but the place should be in great shape in coming years. Huge flocks of feathered friends populate the central ponds, making for a pleasant stroll for birdwatchers. For a new perspective on Moscow’s nightlife, check out the nocturnal animal exhibit. Other highlights include the big cats (featuring Siberian tigers) and the polar bears. For more four-legged fun, follow the footbridge to see exhibits featuring animals from each continent.
