GMAT Critical Reasoning (CR) | Re: A variety of different foods offered in multiple feeders

Although, option E clearly is the one superior to all others. But, I fail to see the reasoning behind saying,

More Feeders in the Area ->> More likely they are to be dominated by a flock of a single type of bird.

and vice-versa, Less Feeders ->> Less likely they are to be dominated by a flock of a single type of bird (Not said by the stimulus, but implied.)

Can anyone please thrown some light on this.

Many Thanks
...
