Researchers have found that some unprotected areas outside of a national park that was designed to protect birds have substantially higher numbers of certain bird species than comparable areas inside the park.

"Surprising" Phenomenon
Some areas outside of a conservation park have substantially higher populations of certain bird species than the park does.

Objective
The correct answer will be a hypothesis that explains why certain species are more prevalent outside the park than inside the park. The explanation must account for some quirk about the species themselves, or some quirk about the park that makes it less hospitable to these species than one would assume.

A
Moose are much more prevalent inside the park, where hunting is prohibited, than outside the park, and moose eat much of the food that the birds need to survive.
The park has a moose problem, which reduces food available for the birds. This isn’t true of areas outside the park, hence why certain bird species make their homes there.
B
The researchers also found that some unprotected areas outside of the park have substantially higher numbers of certain reptile species than comparable areas inside the park.
Rather than clearing anything up about the birds, we also have to account for reptiles. We want something that addresses the surprising fact about birds.
C
Researchers tagged a large number of birds inside the park; three months later some of these birds were recaptured outside the park.
Why did the birds leave? We’re looking for something that tells us why birds prefer to live outside the park.
D
Both inside the park and just outside of it, there are riverside areas containing willows and other waterside growth that the bird species thrive on.
This points to a similarity between the two areas in question. We need a difference that helps explain why some birds prefer not to live in the protected park.
E
The park was designed to protect endangered bird species, but some of the bird species that are present in higher numbers in the unprotected areas are also endangered.
Why don’t those birds go into the park? Like (D), this is missing a comparative aspect between the park and the unprotected areas.
