Answer 1

They flash their pearly whites as they smile down on you while they **** on your head from above; it's all about good luck!

Answer 2

they arent really teeth since they arent made of enamal, but they are called 'tomia'.  they need them to cut thru plant material and also hold onto bugs/snails/small lizards, things like that.

and i think most birds do have them, just smaller birds would have smaller ones.. but not 100% sure on that one.

Answer 3

geese have teeth so they can rip up all the beautiful geraniums i planted at my parents grave in the cemetary    **&&%%** geese!

Answer 4

They don't really.  Geese have serrations on the edges of their bills which are sort-of tooth-like to help them bite off the grass that they eat.

Answer 5

1) BILLS: The shape of the bill (not beak) is very distinctive in waterfowl. The bill has the upper and lower mandible. Canada Geese do not have teeth made of bone, but have transverse tooth-like ridges (serrated) of cartilage (protuberances/smooth) lined up against mandibles. These ridges help to pull up roots and vegetation from the bottom of ponds, and pull up grasses. The Canada goose does not chew its food, yet swallows the food whole, and gravel in the digestive system breaks up the food particles. The nostrils need to be cleaned to prevent clogging and respiratory infections. The goose will clean its nostrils by repeatedly blowing hard into the water. When drinking water, geese will use the bill to lift the water into the mouth, and then toss its head back to let the water run down its throat.

Answer 6

Birds don't have teeth..they don't even have jaw bones which can hold teeth.  Some waterfowl..ducks, geese etc. do have serrated bills..which might resemble tiny little teeth.
