Red-winged blackbirds loses his territory and loses his harem when its wings are turned from orange to black. Males" mating success is highly variable in many species, and almost always more variable than females. ^ this accounts for much of males" advertising and fighting. Almost 90% males do not reproduce offspring. Huge variability in male reproductive success and less in females. Females often produce fewer young in their lifetime compared to males. Her fitness is limited by resources not access to mates. Males fitness is limited by his access to mates but he can sire a limitless number of offspring. Females hit a plateau in reproducing when they mate with a certain number of males whereas males"s fitness continues to increase as they continue to reproduce.
