late at night, believe me!
The other night, I was chatting to a friend outside my house at about 10pm when I heard a flapping noise followed by a Pterodactyl swooping out of a tree, soaring over the house and returning to the tree.
Of course, there are no Pterodactyls anymore (except perhaps in some mad scientist's lab) so in fact what I saw was a Large Flying Fox or Pteropus vampyrus, the largest species of bat.
Despite its name, it is in fact a fruit-eater, not a vampire. However, the first time you see a bat with a 1.5 metre wingspan is really something, I can tell you!
I shudder to think of the impression made by a group of Pterodactyls, with their 10 metre wingspan.
