Dear EJ;- Yes, the wattle on Porkus aeronauticus does somewhat resemble a Turkey wattle. It develops between the neck and collar bone during the mating season. Its color attracts the opposite sex; however the wattle itself works as a sounding chamber, enabling P.a. to change his usual "oink" or "umfph" to a sexual "yii-eee" which, as anyone can see, is a most attractive sound.
