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.

In this study, we investigated potential cues determining choice of mate by female Red-winged Blackbirds (Agelaius phoeniceus) by examining male and nest-site characteristics that (i) affect the reproductive success of females, (ii) can be assessed by females prior to mating, and (iii) vary among potential mates, in 1983–1985. The 17 characteristics considered reflected the accessibility of redwing nests to mammalian predators and to Marsh Wrens (Cistothorus palustris), the importance of cooperation between female redwings in nest defense, and the paternal quality (feeding and defense of nestlings), genetic quality, physical condition, and size of redwing males. Only 4 characteristics, distance to nearest wren nest, distance to nearest simultaneously active conspecific nest, height of vegetation supporting the nest, and nest defense effort of males, met all of the above criteria in at least 1 year. Of these, proximity to wren nests appeared to satisfy the requirements most consistently in time and space, and thus might be the most likely to affect female redwing choice of mate. However, experimental manipulations are needed to ascertain whether any of these characteristics are cues of female mate choice in Red-winged Blackbirds.
