“Mallards, for instance, have a surplus of males compared to females. Because they are monogamous in nature, those extra drakes that do not find a mate often disrupt pair bonds or compete for resources without contributing to reproduction.”
So, taking more drakes may actually ease pressure on females during the high-stress breeding season.
“Harvest of males at current levels, or even if we increased it twofold, would have no impact and might have a positive impact on the population overall,” he said.
Hens have their own equation. Adult females drive reproduction, so their survival matters more.
“For most species, our hunter harvest rates for hens are so low that there’s still not much of an impact,” said Arnold. “We sometimes worry about pintails and yet we’re only harvesting around 3% of the adult females. We aren’t concerned about harvesting females in the big picture—we actually need to harvest them to estimate survival, abundance, and reproductive success. But compared to all of the other factors that kill hens, hunting does not have much of an influence.”
The science says that while hunting does remove birds, it’s not the factor driving overall population declines or increases. Causes such as predation, disease, and other natural agents exert far greater pressure on their ability to survive.

More seriously, I envy you those pretty shrimp. Glad you haven't been crowed out of all your spots.
