AbstractIn many species of birds, parental care is provided by both parents to maximize offspring survival, and there may be important trade-offs between maximizing food gathering and nest protection during the nesting period. The role of parental care in determining reproductive success was investigated in Wood Storks (Mycteria americana), and specifically how the trade-off between frequency and duration of foraging trips, and nest protection has contributed to the nesting outcome. Parental behavior of 85 pairs of Wood Storks was monitored throughout the nesting season in two breeding colonies in Palm Beach County, Florida. Wood Storks have gradually increased the frequency, but not the duration, of foraging trips as chicks developed. The ratio of hatchlings to fledglings was positively associated with the frequency of foraging trips during late chick development. Intra-specific aggressions resulting in nest takeovers have affected 32 % of the nests under study. Occurrence of nest takeovers have been higher for later-breeding pairs, and was happened primarily in the first few weeks of incubation, but was not affected by the degree of joint nest attendance of both parents. These results establish a functional link between parental effort and reproductive outcome in Wood Storks, and highlight the importance of frequent foraging trips, but not nest attendance, by parents.

Males And Females

Some female red-winged blackbird individuals laid as many as four or five clutches in a single breeding season. Renesting attempts followed nesting failures and high renesting rates were characteristic of unsuccessful females. Most renesting female redwings exhibited a strong territory tenacity. However, some females renested in a different territory and I tried to determine why these individuals moved. Since certain birds always moved more between their renesting attempts than others, the female tendency to move is probably intrinsically determined. Extrinsic factors such as the density of nest predators, male age, and harem size did not influence female movements.The strong site tenacity of female redwings has probably been favoured by (1) advantages of familiarity with the habitat, and (2) strong selection on females for mate and harem fidelity which can be achieved most efficiently when males and females return to their original territories. Renesting with the same male and females from the same harem should increase female's reproductive success because cooperation in nest defense is more efficient between familiar birds. The strong tendency of females to renest in the same area in consecutive years significantly influences mating success of males because new males "inherit" harems of previous territory holders.
