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. ████████ ███ ███████ ██████ █████ ██████ ████████ ████ ██████ ████ ███ ███████ █████████ ██ ███ ███████ █████ ██████ ████████ ███ █████ ███ ████ ██████ █ ███████ ██ ███ ████████ ██████████ ████████ █ ███████ █████ █ ███████ ████ ████ ██ █████ ██████ ███ ██████████ █████ ██████ ████████ ████ ███ █████ ███ ███████ ████ █████████ ██ █ ██████ ███████ ███████ ███ ███████ █████ █████████ ██████ █████████ █████ ███ ████ ███ █████ █████████ ██████ ████████ ████ ██ ███████████ ███ ███ ████ ██████ ██████ ███ █████ ██ █████ ██████████ ███████
Summary
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.
Notable Assumptions
The argument’s 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.
