Birds startled by potential predators generally try to take cover in nearby vegetation. Yet many birds that feed at bird feeders placed in suburban gardens are killed when, thus startled, they fly away from the vegetation in the gardens and into the windowpanes of nearby houses.

"Surprising" Phenomenon
Birds usually hide in vegetation when startled, but tend to flee vegetation when startled in suburban gardens.

Objective
A hypothesis explaining this behavior must imply a difference between startled birds in general and birds startled at feeders in suburban gardens. This difference must explain why birds in suburban gardens seem to buck the trend by fleeing vegetation and colliding with windows.

A
Predator attacks are as likely to occur at bird feeders surrounded by dense vegetation as they are at feeders surrounded by little or no vegetation.
This eliminates an irrelevant distinction. The author states or implies no difference between feeders surrounded by dense vegetation and those surrounded by little to no vegetation, nor suggests to which category suburban garden feeders belong.
B
The bird feeders in some suburban gardens are placed at a considerable distance from the houses.
This deepens the mystery. If the birds are long distances from the windows when startled, their collision with them seems less coincidental—yet no more clear.
C
Large birds are as likely as small birds to fly into windowpanes.
This is irrelevant information. The author makes no distinction between large and small birds, so their similarity in this respect does nothing to explain the birds’ behavior.
D
Most of the birds startled while feeding at bird feeders placed in suburban gardens are startled by loud noises rather than by predators.
This is an irrelevant distinction. There is no suggestion that birds startled by noises are less likely to seek vegetation than birds startled by predators.
E
The windowpanes of many houses clearly reflect surrounding vegetation.
This explains the tendency of birds at suburban feeders to collide with windows. The birds mistake the windowpanes for vegetation, colliding with them accidentally.
