What are Piscivorous birds?
Abstract. Piscivorous birds have received much attention with respect to competition with fisheries for resources. The majority of studies have been focused on cormorants Phalacrocoracidae, while predation by other piscivorous bird species has often been overlooked.

Why are larger birds more likely to eat insects?
One reason that the larger birds do well in cities is that they are more likely to benefit from human-created foods (petfood, garbage, foodscraps and carrion) than small birds, which mostly eat insects. Small birds generally can’t compete with larger birds for resources.
