The author hypothesizes that last year’s mild winter caused this year’s larger-than-usual bird population. This is based on the fact that the mild winter allowed a higher proportion of birds to forage naturally rather than forage at a feeder. In addition, the mild winter also allowed many bird species to avoid having to migrate south during winter, which reduced typical deaths from having to migrate.

The author assumes that there’s no other explanation for why there was a larger-than-usual bird population. The author also assumes that a higher proportion of birds forage naturally rather than by using a feeder is something that is beneficial to bird population.

This doesn’t help establish a causal relationship between a mild winter and the larger bird population. (A) is consistent with a completely coincidental relationship between weather patterns and bird populations.

Different mating behaviors have no clear relationship to increased population. In any case, the premises already show how removing the need to migrate south helps increase populations by reducing attrition. We don’t need additional support regarding this aspect of the argument.

This helps establish a causal mechanism between having a lower proportion feeding at bird feeders and a larger population. By allowing a lower proportion to feed at feeders, a mild winter helped protect birds from predators.

If anything, this is something negative about a mild winter. If birds that don’t migrate south often exhaust food supplies before spring, this might suggest a mild winter could make survival more difficult.

We know the mild winter allowed a lower proportion to feed at feeders. The fact that some birds might still visit feeders despite not needing to doesn’t change or add to our understanding of the premises and how they relate to the conclusion.
