Line 48:

These features that the stimulus has to obtain in order to trigger a resulting FAP were then given the official term of Sign Stimuli. Scientists came to the realization that there must be an innate deciphering method that the goose goes through in order to determine a suitable sign stimulus. This was defined as an [[Innate releasing mechanism|Innate Releasing Mechanism]] (IRM). The goose's IRM when put to the test in the natural world not being manipulated by scientific experimentation is almost always efficient in getting the desired item of an egg back into the nest.<ref name=":0" />

=== Other Examplesexamples of Signsign Stimulistimuli===

More examples of Signsign Stimulistimuli include:

* The red mark on the mother's beak recognized by [[kelp gull]] chicks.

* Light polarization patterns recognized by [[Mayfly|mayflies]] when they are deciding where to drop their eggs.

* The presence of a female [[Centrocercus|Sagesage Grousegrouse]] that causes males to exhibit a strut pattern display in order to attract the female during breeding season.<ref>{{Cite journal |last=Haven Wiley |first=R. |date=1973 |title=The Strut Display of Male Sage Grouse: A "Fixed" Action Pattern |journal=Behaviour |volume=47 |issue=1/2 |pages=129–152 |jstor=4533545 |doi=10.1163/156853973X00319}}</ref>
