The males of this species (
Calidris pugnax) are highly unique as they appear to have three different “
genders” which, unlike other species, do not appear to be triggered by environmental inputs. They are genetic. Lank calls these three
morphs [i.e., morphologies]:
• the Territorial aka Independent
• the Wingman aka Satellite
• the female mimics aka Faeder
Crucially, these ‘
genders’ are all heterosexual males who use differing strategies to reproduce with females. The female mimics are not trans lesbians. They are small, low status, low testosterone heterosexual males, tricking females to get sex. They are sneaky [fuɔkers] (SN’s). The scientific name for the SN reproductive strategy is kleptogamy, meaning stolen mating.
