Difference between a crow and a sparrow!

Crows are  known for  their unity. When a crow sees  food grain, it calls all other crows and eat it by sharing.  I have not seen them quarreling for a piece of food.
But on the other hand, beat known quarrelers for food are dogs. 

But sparrows are also do the same thing with a small difference. When food grains are more, there will be no fighting. But when it is  very less, then one strong sparrow  will chase out all others and eat the grain alone. You want the proof? Look at the video that I have captured!
