A young common grass snake
Based on your description, the snake you are referring to is likely the Eastern garter snake (Thamnophis sirtalis). This species is known for its tan body, black head, and thin yellow band around its head, making it easily recognizable.
A mallard is a bird that has an iridescent green head and brown on the body. The ring necked pheasant is another bird with a brown body, and an iridescent green head.
I have know clue but i wanna know cause my brother saw one in our barn he described it as gray body black head and a lil bit to 17 ft!!
Ring neck snake
the natural colouration of a budgie is a green body with a yellow head
not exactly, it is just the color
Sounds like a ringneck snake, they are completely harmless and some of the most beautiful (in my opinion) of the North American snakes.
No, it does not because it will bleed to death. As with other vertebrates, a snake's brain needs to have blood pumped through it by the heart. If the head its removed from the blood supply, the brain can no longer function.
a coin
If you saw one it depends where you live, but it could be one of the following: green tree snake: http://las.new-England.net.au/wp-content/uploads/2007/03/images20070304-035-treeSnake-sml.jpg http://www.tvwc.org/AssetsGreenTreeSnake.jpg green tree python: http://www.kingsnake.com/ihs/I.H.S.%202005%20PHOTO%20CONTESTHeat%20pits%20of%20the%20green%20tree%20python%20-%20Michael%20D.%20Kern%20-%20IN%20CAPTIVITY,%20SM.jpg rough green snake: http://www.wilddelaware.com/wp-contentrough-green-snake-11832.jpg natal green snake: http://api.ning.com/files/L1ySGyMwLZ3hID057bBHbPN6Eqw8ML160RN4P6rDPxM_NatalGreenSnake.jpg Asian green snake: http://www.dekayi.info/R_I_P_%20Green%20snake_filestree2.jpg Hope this helps.
probably a coral snake or something
Coral snakes are relatively small snakes. They are tri-colors - yellow, red and black. The coral snake distinguishes itself from copycats, such as the king snake, by the coloration of the stripes. If the yellow stripes touch the red stripes the snake is a coral snake.
