Studies of two species of blackbirds showed that red-winged blackbirds establish nests mostly on the edges of marshes, but also extend throughout the marsh if yellow-headed blackbirds are absent. Yellow-headed blackbirds can nest only in the middle of marshes, regardless of the presence of red-winged blackbirds, because they require wetter habitat. Based on this, which of the following statements are true? Select all that apply. The realized niches of the two species differ. OThe fundamental niche of red-winged blackbirds is larger than its realized niche. The fundamental niche of red-winged blackbirds is larger than the fundamental niche of yellow-headed blackbirds. The fundamental and the realized niches of red-winged blackbirds are the same. The fundamental and the realized niches of yellow-headed blackbirds are the same.
