In wattled jacanas, there is indeed a female-biased operational sex ratio, and females do recycle faster than males because they abandon the eggs to the males, who then take on the responsibility of paternal care. This system is quite the opposite of many other bird species, where males compete over females and do not typically take on the primary role in nurturing the offspring.
