Step-by-step explanation:
Among the options provided (racoon, feral hog, fire ant, and starling), the animal that is probably not an invasive species in northeast Texas would be the raccoon. Raccoons are native to North America, including Texas, and typically do not fall under the category of invasive species.
In contrast, feral hogs, fire ants, and starlings have been introduced to the area from different parts of the world and can cause significant ecological disruption, making them invasive species.
The European starling (Sturnus vulgaris), in particular, is known to compete with native bird species for nest holes and is considered an invasive species in the region.
