Gorillas sleep in nests. They make a new nest every day, even if there is nothing wrong with the old one. The scientific name for the gorilla is ‘Gorilla gorilla’. This is an example of a 'tautonym'.
Other examples include ‘Bison bison’ and ‘Iguana iguana’.
‘Rattus rattus’ is the scientific name for the rat.
‘Oriolus oriolus’ is the scientific name for the golden oriole.
‘Cygnus cygnus’ is the scientific name for the whooper swan.
‘Puffinus puffinus’ is the scientific name for the Manx shearwater.
The oldest bird in the world was a Manx shearwater. One was tagged in Cokeland Island, Northern Ireland as an adult (at least 5 years old) on July 1953 and trapped again in July 2003 - so it lived for over 55 years!!!( or the birds have discovered a way of swapping rings) lol
