I like taking little lessons from birds. This guys conservation status is termed 'Least Concern', in other words its successful in this changing world.Its an Omnivore!
Omnivores (from Latin: omne all, everything; vorare to devour) are species that eat both plants and animals as their primary food source. They are opportunistic, feeders not specifically adapted to eat and digest either meat or plant material exclusively. Pigs are an example of an omnivore.
When the fishing is good the kiskadee eats fish, when their are a lot of bugs they eat bugs, when the trees fruit they eat fruit.
Not likely to starve to death :-)
Humans are omnivores.
