Toronto Zoo asks visitors to quiet down near protective grey-necked crowned cranes.

The Toronto Zoo is asking visitors to be quiet and respectful around a nesting pair of grey-necked crowned cranes named Huckleberry and Baroness in the African Rainforest Pavilion. The cranes are overprotective of their nest, so the zoo advises people to stay behind barriers and keep noise down. These cranes are native to parts of eastern Africa but face threats like habitat loss and commercial trade.
