A New Species

Abstract We describe a new species of shorebird, tentatively referred to the family Charadriidae, from the Huadian Formation (Middle Eocene) in Jilin Province, China. In general morphology the specimen closely matches that of an extant charadriid, and corresponds in size to the Killdeer (Charadrius vociferus). If correctly identified this is the oldest record of the Charadriidae. The Middle Eocene paleoenvironment of the Huadian region is thought to have resembled a subtropical swamp. Un Ave Playera de China del Eoceno Medio Resumen. Describimos una nueva especie de ave playera, tentativamente clasificada como de la Familia Charadriidae, de la Formación Huadian (Eoceno Medio) en la Provincia de Jilin, China. En términos de morfología general, el ejemplar coincide mayormente con la morfología de un charádrido actual, y se asemeja en tamaño a Charadrius vociferus. Si la identificación es correcta, este representa el registro más antiguo para la Familia Charadriidae. El paleoambiente del Eoceno Medio de la región de Huadian se asemejaba probablemente a un pantano subtropical.

Charadrius Vociferus

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 a successful nesting attempt was also equal for the sexes. However, early parental effort expenditures by females, early mating effort expenditures by males, and high rates of nest failure combine to result in female reproductive energy expenditures being significantly higher over the breeding season. This suggests that energy expenditure alone is not adequate for accurate comparisons of the relative investments of the sexes. Studies investigating male and female investments need to consider the degree and pattern of nest failures along with patterns of energy expenditure. The advantages to male and female Killdeer of sharing parental care is demonstrated using adult removal experiments. In general, a deserted parent expends more energy in parental effort than a bi-parental parent and has significantly lower reproductive success. However, males are able to hatch chicks, whereas females lose or abandon their nests within a few days of mate removal. Thus, monogamy in Killdeer appears to result from high nest failure rates, the necessity of two parents for any reproductive success, and the generalizable nature of Killdeer parental care.

The Relationship

Four species of trematodes of the family Eucotylidae were collected from birds in British Columbia. Eucotyle castanea n.sp. from Melanitta deglandi (Bonaparte) differs from other members of the genus mainly by the presence, throughout its parenchyma, of a reddish-brown pigment. E. cohni Skrjabin, 1924 was recovered from Podiceps grisegena holböllii Reinhardt, Clangula hyemalis (Linnaeus), Bucephala clanguia (Linneaus), and Padiceps aurittis (Linnaeus). E. warreni Schell, 1967 was collected from Bucephala islandica (Gmelin) and Tanaisia fedtschenkoi Skrjabin, 1924 from Charadrius vociferus Linnaeus. This is the first record of the occurrence of these parasite species in Canada.The structure of the cirrus sac in E. castanea and E. cohni and the excretory system of the latter species are described. The relationship between Eucotyle and Tanaisia is discussed and a key to the species of Eucotyle is included.
