Besides laying eggs in her own nest, any female wood duck will lay an egg in the nest of another female wood duck if she sees the other duck leaving her nest. Under natural nesting conditions, this parasitic behavior is relatively rare because the ducks’ nests are well hidden. However, when people put up nesting boxes to help the ducks breed, they actually undercut the ducks’ reproductive efforts. These nesting boxes become so crowded with extra eggs that few, if any, of the eggs in those boxes hatch.

Summary
Any female wood duck will lay an egg in the nest of another female wood duck if she sees the other duck leave her nest. Under natural nesting conditions, this behavior is rare because wood duck nests are usually well hidden. However, nesting boxes put up by people undercut the wood duck’s reproductive efforts. Why? Because the nesting boxes become so crowded with eggs that few of them will ever hatch.

Strongly Supported Conclusions
If the nesting boxes put up by people were better hidden, then the boxes would be more successful in aiding the wood duck’s reproductive efforts.

A
Female wood ducks will establish nests in nest boxes only when natural nesting sites are not available.
We don’t know what causes a female wood duck to establish a nest in a nesting box. We only know that female wood ducks will lay eggs in another duck’s nest if she sees that duck leave the nest.
B
Nesting female wood ducks who often see other female wood ducks are the most successful in their breeding efforts.
We don’t know which female wood ducks reproduce most successfully.
C
The nesting boxes for wood ducks have less space for eggs than do natural nesting sites.
We don’t know whether the nesting boxes have less space. We only know that the nesting boxes tend to be overcrowded, but that does not imply that these nesting sights are smaller than natural nesting sites.
D
The nesting boxes would be more effective in helping wood ducks breed if they were less visible to other wood ducks than they currently are.
The argument concludes that the nesting boxes undercut the duck’s reproductive efforts because the boxes become overcrowded. If the cause for overcrowding the nests were reduced, then the effect of undermining reproductive efforts would also be reduced.
E
Nesting boxes are needed to supplement the natural nesting sites of wood ducks because of the destruction of much of the ducks’ habitat.
We don’t know whether the nesting boxes are needed, and we don’t know whether the wood ducks’ habitat is being destroyed.
