According to the known topics:

There are 14 rabbits in mother rabbit's house. Mother rabbit and seven rabbits are crossing the river.

That is, 7+ 1=8 rabbits crossed the river.

So there are rabbits by the river, which is the total number of rabbits MINUS the number of rabbits crossing the river, which is 14-8=6 rabbits.

Verification:

Rabbits crossing the river and along the river are the total number of rabbits, so 6+7+ 1= 14. That is, it meets the known conditions of the topic, so the answer is 6 rabbits.
