The male sage grouse has air sacs that, when not inflated, lie hidden beneath the grouse’s neck feathers. During its spring courtship ritual, the male sage grouse inflates these air sacs and displays them to the female sage grouse. Some scientists hypothesize that this courtship ritual serves as a means for female sage grouse to select healthy mates.

Summarize Argument: Phenomenon-Hypothesis
Scientists hypothesize male sage grouse inflate their air sacs during a courting ritual so that female sage grouse can select healthy mates. They provide no evidence for this claim.

Notable Assumptions
The scientists assume that inflated air sacs either signify health in themselves, or demonstrate some feature that signify health. They also assume female sage grouse can determine which males are healthy and which aren’t. Lastly, the scientists assume the female sage grouse are more likely to choose the healthy males.

A
Some female sage grouse mate with unhealthy male sage grouse.
This is irrelevant. Perhaps those were the only unhealthy male sage grouse left.
B
When diseased male sage grouse were treated with antibiotics, they were not selected by female sage grouse during the courtship ritual.
We have no idea what effect antibiotics have.
C
Some healthy male sage grouse do not inflate their air sacs as part of the courtship ritual.
Are those males chosen by the females? We would need to know in order for this to be a strengthener.
D
Male sage grouse are prone to parasitic infections that exhibit symptoms visible on the birds’ air sacs.
Females can note parasitic infections when male sage grouse inflate their air sacs. Thus, they are quite likely looking to see which males are healthy during the courting ritual.
E
The sage grouse is commonly afflicted with a strain of malaria that tends to change as the organism that causes it undergoes mutation.
This has nothing to do with air sacs.
