Why is it that species which seem very similar choose different habitats? The species I am currently wondering about are the White Ibis and the Glossy Ibis. Here, in Florida, the Glossy Ibis is almost never found away from wetlands whereas the White Ibis is found almost anywhere -- in wetlands, but also in parking lots and everywhere in between. Their body plan (including the bill) seems almost identical and I imagine they either do or could take very similar prey. Then why this big difference in habitat choice? Or rather why is one species so restricted and the other not?
