man was annoyed to discover that a pigeon was inside his home and made a big mess.

Stian Fjelldal of Oslo, Norway, said that he forgot to close his window when he left for work. 

When he returned to his apartment on Monday, he found the pigeon in the corner of his kitchen.

He decided to take video of the mess it made, which included feathers and bird droppings scattered on the floor. When the bird saw Fjelldal, it began flapping its wings and flew out the window.

After a few seconds, the pigeon flew out of the house and Fjelldal recorded the mess it made.

Fjelldal began laughing when he saw that the bird made itself a nest and laid an egg inside the frying pan, which was on his stove.

Fjelldal who works for the Norwegian Environment Agency, said that he will take the egg to work and he hopes it will contribute to science.
