http://7sage.com/lsat_explanations/lsat-20-section-1-question-06/I understand why the answer (D) is correct, but not sure why the answer choice (C) is incorrect. Is it because the answer choice makes an assumption that natural nesting sites will be less crowded than the nesting boxes? I thought this can be a logical conclusion from the passage rather than just assumption. Please explain me why (D) is a better answer choice than (C).

D is the correct answer because it connects the ideas about visibility and ducks laying eggs. That is, the boxes nests are becoming overcrowded with the "parasitic behavior" of other ducks laying eggs there because they are not as well hidden as the natural nests. While this may not be a 100% validly drawn inference, it is pretty well supported which is what we are looking for in a MSS type question.
Hope this helps!
