Reverse sexual dimorphism is the tendency for certain bird species to reverse the normal trend for the male to be larger than the female. It is particularly found in Birds of Prey, for example the peregrine falcon whose adult male weighs in at around 660g whereas the female is over 1kg. The physical size differential is also very obvious, the two birds looking almost like different species.

Sexual dimorphism describes the physiological, behavioral, and morphological differences between the sexes of the same species. Larger primates like the gorilla and humans tend to be more dimorphic than smaller species with males being at the head of social organizations due to their larger size.
