ENERGY EXPENDITURE IN REPRODUCTIVE EFFORT OF MALE AND FEMALE KILLDEER (CHARADRIUS VOCIFERUS)

Killdeer (Charadrius vociferus) Science Article 1

abstract

The reproductive investment strategies of the sexes during the breeding season are detailed for Killdeer (Charadrius vociferus), a monogamous plover. I measured the energy investments of the sexes in reproductive, mating, and parental effort. As predicted, males expend more mating effort than females; however, the sexes expend equal amounts of parental effort. Total energy expenditure in reproductive effort (mating and parental effort) during asuccessful nesting attempt was also equal for the sexes
