“…Thus, acceptance of additional offspring may have little effect on the recipients. Heusman (1972) and Clawson et al (1979) found that wood duck young survived equally well in "parasitized" and "unparasitized" broods. Morse and Wight (1969) and Heusman et al (1980) observed comparable hatching success in "parasitized" and "normal" wood duck clutches.…”

pre-hatch brood amalgamation, whereby a female lays her eggs in the nest of another female and the recipient thereafter provides all further care of the eggs and resulting offspring, and (ii) post-hatch brood amalgamation, whereby a female abandons or loses her young to another female after hatch, and the recipient subsequently tends the foster young. Some authors have viewed these behaviours as accidental or aberrant and of little evolutionary significance. More recently, a number of alternative hypotheses have been suggested. However, few of these hypotheses have been contrasted as viable alternatives and tested in the field, largely because an appropriate theoretical framework is lacking. We analyze the frequency of occurrence of brood amalgamation in North American anatids. We also review the hypotheses that have been proposed to explain these behaviours and erect a theoretical framework which applies to the evolution of both pre-hatch and post-hatch brood amalgamation, and which may apply to species other than those of the Anatidae. Finally, we show that the occurrence of brood amalgamation in North American waterfowl may be associated with low relative resource availability and K-type life-history traits. EADIE, J.

Deux formes de fusion de couvCes se produisent frCquemment chez plusieurs espkces d'oiseaux de rivage nord-amCricains : ( i ) fusion des couvCes avant 1'Cclosion : certaines femelles pondent leurs oeufs dans le nid d'une autre femelle et la femelle rCcipiendaire donne alors tous les soins aux oeufs et aux oisillons qui en rCsultent et (ii) fusion des couvCes aprks 1'Cclosion :certaines femelles abandonnent leurs oisillons a une autre femelle ou les perdent aprks 1'Cclosion et la femelle rkcipiendaire assure alors les soins aux petits qu'elle adopte. Certains auteurs considkrent ces comportements comme accidentels ou aberrants et de peu d'importance Cvolutive. Plus rCcemment, d'autres hypothkses ont Ct C proposCes, mais peu ont Ct C retenues ou CprouvCes en nature, en grande partie parce qu'elles ne sont reliCes a aucun cadre thCorique appropriC. On trouvera ici une analyse de la frCquence de fusion des couvCes chez les Anatidae nord-amkricains, de meme qu'une rCvision des hypothkses proposCes pour expliquer ces comportements; cette rCvision nous permet d'Ctablir un cadre thCorique qui peut s'appliquer a 1'Cvolution de la fusion prC-Cclosion et de la fusion post-Cclosion des couvCes et qui peut convenir aussi a des espkces autres que les Anatidae. I1 est possible que la fusion des couvCes chez la sauvagine nord-amCricaine soit associCe a une disponibilitk relative faible des ressources et a des caractkristiques d'une stratCgie dkmographique de type K.[Traduit par la revue]

Conspecific brood parasitism (CBP), defined as parasitic laying of eggs in a conspecific nest without providing parental care, occurs in insects, fishes, amphibians, and many birds. Numerous factors have been proposed to influence the evolution of CBP, including nest site limitation; effects of brood size, laying order, or parasitic status on offspring survival; randomness of parasitic egg distribution; adult life-history trade-offs; and variation in parental female quality or risk of nest predation. However, few theoretical studies consider multiple possible types of parasitism or the interplay between evolution of parasitism and population dynamics. We review existing theory of CBP and develop a synthetic modeling approach to ask how best-of-a-bad job parasitism, separate-strategies parasitism (in which females either nest or parasitize), and joint-strategies parasitism (in which females can both nest and parasitize) differ in their evolutionary conditions and impacts on population dynamics using an adaptive dynamics framework including multivariate traits. CBP can either stabilize or destabilize population dynamics in different scenarios, and the role of comparable parameters on evolutionarily stable strategy parasitism rate, equilibrium population size, and population stability can differ for the different modes of parasitism.

“…The lower body mass of incubating females captured in nest boxes versus females and males captured in traps earlier in the season apparently reflected a loss associated with the reproductive cost of incubation (Hepp et al, 1990) rather than an adverse effect from lead. Compared with normal nests, the abandonment rate of dump nests was higher (Bellrose et al, 1964;Grice and Rogers, 1965) or was slightly lower (Heusmann, 1972). The large proportion of dump nests suggested a relatively high density of wood ducks in the area; however, the nest boxes generally were conspicuous and closely spaced together, two prerequisites for increasing dump nesting or brood parasitism (Semel et al, 1990).…”

“…Of 66 clutches, 31 (47%) contained >15 eggs and were classified as dump nests because of the high probability that more than one female had laid eggs in these nests (Grice and Rogers, 1965;Heusmann, 1972;Bellrose, 1976). Of these, 81 boxes (46%) were active and their 83 clutches contained 1,148 eggs.…”

Accumulation and effects of lead and cadmium on wood ducks near a mining and smelting complex in Idaho

et al. 1993

: A study of wood ducks (Aix sponsa) was conducted along the Coeur d'Alene River system in northern Idaho in 1986 and 1987. Most of this area has been subjected to severe contamination from lead and other metals from mining and smelting since the 1880s. In 1986, a preliminary study of wood duck nesting was conducted in the contaminated area; incubating hens captured in nest boxes were bled and weighed. Blood samples were used to determine lead and cadmium concentrations and physiological characteristics. In 1987, an intensive study of wood ducks involved trapping and monitoring nest boxes in the contaminated area. Blood and tissue samples were also taken from wood ducks from a reference area without known contamination from metals. Lead levels in blood and tissues of most wood ducks from the contaminated area frequently exceeded those considered hazardous to birds; maximum levels (wet weight) of lead were 8 μg g(-1) in blood and 14 μg g(-1) in liver. Changes in physiological characteristics constituted the only evidence of potentially adverse effects from lead. In the contaminated area, nesting success (55% unadjusted, 35% Mayfield estimate) was less than in other areas where predation was low and nest boxes were used; but lead concentrations and physiological characteristics of blood were similar in successful and unsuccessful hens.Values of ALAD, hemoglobin, and body mass were negatively correlated with blood concentrations of lead, whereas protoporphyrin was positively correlated with lead levels in the blood. Some of the protoporphyrin values (1,091 μg dl(-1) in a male and 756 μg dl(-1) in a female) equalled those associated with lead toxicosis in experimental birds. ALAD activity was low in most birds from the contaminated area; values of 0 were obtained from 11 birds. Lead levels in blood, ALAD, protoporphyrin, and hemoglobin were significantly different between birds from the contaminated and reference areas. Concentrations of lead in ingesta of wood ducks ranged from 0.9 to 610 μg g(-1) in the contaminated area and 0.2 to 0.6 μg g(-1) in the reference area. Levels of cadmium in kidneys of wood ducks ranged from 1μg g(-1) to 20 μg g(-1) in the contaminated area and from only to 0.1 μg g(-1) to 1 μg g(-1) in the reference area. Cadmium concentrations were less than known effect levels.
