Least Sandpiper (Calidris minutilla) Science Article 1 abstract Differential distribution of nonbreeding Least Sandpipers (Calidris minutilla) according to sex,bill, and wing length was documented using capture data from six locations between California and Ecuador. Thedistribution of age classes did not vary with latitude. Females, which are slightly larger than males, migrated furthersouth. Wing length increased […]

NESTING BIOLOGY OF BLACK SKIMMERS, LARGE-BILLED TERNS, AND YELLOW-BILLED TERNS IN AMAZONIAN BRAZIL
Large-billed Tern (Phaetusa simplex) Science Article 1 abstract Nests of Black Skimmers (Rynchops niger) (n = 37), Large-billed Terns (Phaetusa simplex) (n = 121), and Yellow-billed Terns (Sterna superciliaris) (n = 16) on an exposed sandbar in the Trombetas River, Brazil, were monitored during incubation and hatching in 1982. The species were interspersed throughout the […]
Incidental Kill of Dunlin and Killdeer by Strychnine
Killdeer (Charadrius vociferus) Science Article 5 abstract Strychnine poisoning of 36 dunlin (Calidris alpina) and two killdeer (Charadriusvociferus) in Yolo County, California (USA) was documented from 1 1 to 17 December 1990. Birds were found dead on a field containing treated wheat seeds (337 zg strychnine/g seed) in postures consistent with the known physiopathology of […]
Nest fate and vegetation characteristics for Snowy Plover and Killdeer in Colorado, USA
Killdeer (Charadrius vociferus) Science Article 4 abstract We quantified vegetation characteristics at nest sites of Snowy Plovers (Charadrius alexandrinus) and Killdeers (C. vociferus) in south-eastern Colorado during 1995 to assessinterspecific differences in nesting habitat and determine whether habitat characteristics influenced nest fate. Killdeers nested in areas with significantly more grass, litter, and vegetation within 10 […]
EASTERN WOOD-PEWEE ATTEMPTS TO FEED KILLDEER CHICKS
Killdeer (Charadrius vociferus) Science Article 2 abstract In July 1988, a wild Eastern Wood-Pewee (Contopus virens) was observed attempting to feed two captive Killdeer (Charadrius vociferus) chicks throughout one day. The Killdeer were in an open air pen close to a forest edge. This was an unusual adoption, involving an altricial species feeding precocial young. […]
Diet of nesting Killdeer in North Dakota
Killdeer (Charadrius vociferus) Science Article 3 abstract Killdeer (Charadrius vociferous) is one of the most widespread of all North American shorebirds and, unlike other shorebirds, tolerates a wide variety of open inland habitats in addition to the shores of coastal and inland water. JEANNE M. FAIR, PATRICIA L. KENNEDY, AND LOWELL C. MCEWEN, Wilson Bull., […]
SPACE USE OF KILLDEER AT A GREAT BASIN BREEDING AREA
Killdeer (Charadrius vociferus) Science Article 6 abstract Wetland conservation efforts require knowledge of space use by a diversity of waterbirds. However,determining space use of animals requires intensive monitoring of individual organisms. Often, activity patternsduring much of the annual cycle are neglected in analyses of home range and habitat use. From 1995
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 […]
Status of Kentish Plover(Charadrius alexandrinus) in Hungary
Kentish Plover (Charadrius alexandrinus) Science Article 7 abstract Population size, distribution and reproductive success of Kentish Plovers in Hungary are sum-marised. 105-140 pairs bred in 1988-1992. Two breeding sites (Miklapuszta and Southern Hun-gary) contained the bulk of the population, with 60-80 pairs and 35-40 pairs, respectively. Thenumber of breeding pairs has declined in recent years. […]
The mating system of Kentish Plovers Charadrius alexandrinus
Kentish Plover (Charadrius alexandrinus) Science Article 6 abstract Kentish Plover Charadrius alexandrinus pairs generally re-nest together after the loss of a clutch. In contrast, two females who hatched clutches changed mates before re-nesting, thus proving sequential polyandry. Observations of adults accompanying broods show that females normally desert the brood about a week after hatching. The […]
