Every autumn,there is interesting competition between my family members,pets,and...crows.
The main reason why this competition exists is nut tree.
The main criterion of victory is number of nuts,gathered by participants.
Often winners are crows,because they can gather nuts from the top of the tree,from all the crown, lower branches and ground.
Me and my family used to gather nuts from ground and lower branches.
Our dogs are losers in this competition, because the only available territory for harvest for them is ground.
