The wandering albatross has the largest wingspan of any living bird, typically ranging from 2.51 to 3.5 m (8 ft 3 in to 11 ft 6 in), with a mean span of 3.1 m (10 ft 2 in) in the Bird Island, South Georgia colony and an average of exactly 3 m (9 ft 10 in) in 123 birds measured off the coast of Malabar, New South Wales.

There are around 10,000 different species of birds worldwide.

Ostrich eyes are the largest of any animal that lives on land (though they can’t rival some of the massive creatures that inhabit the depths of the sea). Approximately the size of a billiard ball, their eyes are actually bigger than their brains.
