The song of the yellow warbler signals to other yellow warblers that a particular area has been appropriated by the singer as its own feeding territory. ββββββββ βββ βββββββ ββββββ βββββ ββββββ ββββββββ ββββ ββββββ ββββ βββ βββββββ βββββββββ ββ βββ βββββββ βββββ ββββββ ββββββββ βββ βββββ βββ ββββ ββββββ β βββββββ ββ βββ ββββββββ ββββββββββ ββββββββ β βββββββ βββββ β βββββββ ββββ ββββ ββ βββββ ββββββ βββ ββββββββββ βββββ ββββββ ββββββββ ββββ βββ βββββ βββ βββββββ ββββ βββββββββ ββ β ββββββ βββββββ βββββββ βββ βββββββ βββββ βββββββββ ββββββ βββββββββ βββββ βββ ββββ βββ βββββ βββββββββ ββββββ ββββββββ ββββ ββ βββββββββββ βββ βββ ββββ ββββββ ββββββ βββ βββββ ββ βββββ ββββββββββ βββββββ
When a yellow warbler is molting, it sings a song that stops any other yellow warblers from entering its territory. Therefore, when molting, yellow warblers will have no competition for food within their territory.
The argumentβs premises establish that when a yellow warbler is molting it will not face any competition from other yellow warblers. The conclusion, however, makes a much broader claim that they will not face any competition whatsoever. There is therefore a missing gap, which needs to be filled by some assumption stating that the only completion yellow warblers face are other yellow warblers.
