The great blue heron and the small dark heron are long-legged birds that live in wetlands, like the Everglades in Florida. Laura D’Acunto and colleagues wanted to know how these birds choose an area in which to live. They looked at features of the birds’ habitats, such as the geographic location of the area and how deep the water is during breeding season. They found that although both great blue herons and small dark herons prefer areas that have standing water for more than 60 days per year, only great blue herons prefer areas with deep water during breeding season, suggesting that __________
Which choice most logically completes the text?
A
having features that are highly attractive to one species will likely cause an area to be avoided by the other species.
B
the effect of water depth on an area’s appeal to the two species increases with the duration of the presence of standing water, but more strongly for great blue herons than for small dark herons.
C
outside of breeding season, both species show a stronger preference for areas with shallower water.
D
merely having standing water for at least a certain number of days per year will not necessarily make an area equally attractive to both species.
