Birds and squirrels compete for the same food sources.
Explanation:
Food is essential for every animal species. Usually, wild animals which live in the wild, take those foods which are present in the forest. But in any case, if the wild animal doesn't get their food in the wild, they might come closer to the human habitat for searching their food. It happens for all wild animals. There are several examples that prove that many times, many wild animals came closer to the human habitat for searching for their foods.
The squirrels came to the bird feeder because they found their food in the bird feeder. It also proves that they are not finding their food correctly in their natural habitat.
