Common yellowthroat
Also known as "Geothlypis trichas," this New World warbler is known for their specific song "twitchy, twitchy, twitchy," and the clear distinguishing feature among male and female Common yellowthroat. The male has a black mask on their face while the female does not. The Common yellowthroat is distributed widely across the United States when in time for breeding, but this warbler tends to inhabit the southeastern region of the US to live (and unfortunately met it ends at a gas station). Though not endangered, the Common yellowthroat has seen a decline due to losing its favorite habitat.
The black mask shown in this dead Common yellowthroat has two purposes, both examples of intrasexual competition. The first purpose is to mark which warbler is a male. Because of the black mask, identification of who is a male is made easy, and therefore, much more likely for the warbler to know who to be way off, or who to challenge should the rival attempt to woo the female. The second purpose is to help the male warbler woo the female. Along with their ritual dance of shaking their tail feathers and singing their twitchy song, there has been a correlation with the preferred choice of a mate being the male with the largest black mask.
