Tufted Titmouse are regulars at backyard bird feeders, especially in winter. They prefer sunflower seeds but will eat suet, peanuts, and other seeds as well. Find out more about what this bird likes to eat and what feeder is best by using the Project FeederWatch Common Feeder Birds bird list.
What do they eat? They are omnivorous, therefore they eat both plants and little animals. Turtles look for creatures to eat in the soft mud or sand. Their diet is made up from aquatic insects, earthworms, crabs, crayfish, snails, fish eggs, clams, small fish, millipedes, tadpoles, adult frogs or any other carrion that they may find in the water. The plants they like more are algae.
