Would you classify red squirrels and grey squirrels as specialist or generalists?

Answer 1

Red squirrels are generally considered specialists, as they primarily rely on specific habitats, particularly mature coniferous forests, and have a diet that heavily depends on pine seeds. In contrast, grey squirrels are classified as generalists because they can thrive in a variety of habitats, including urban areas, and have a more diverse diet that includes nuts, fruits, and even bird eggs. This adaptability allows grey squirrels to occupy a wider range of environments compared to red squirrels.
