Pacific and American Golden-Plovers: reflections on conservation needs

American Golden Plover (Pluvialis dominica) Science Article 3 abstract Much has been learned about the biology of Pacific and American Golden-Plovers (Pluvialis fulva and P. dominica)in recent years. However, most of this information does not address conservation-related questionsaffecting the future of these birds. We lack accurate demographic figures (guesstimates of world populationvary more than 30-fold […]

Time budgets and body temperatures of American Golden-Plover chicks in relation to ambient temperature

American Golden Plover (Pluvialis dominica) Science Article 1 abstract We studied time budgets of precocial chicks of American Golden-Plovers (Pluvialisdominica) on the tundra near Churchill, Manitoba, Canada, to assess how time budgetsare influenced by environmental and body temperatures. Foraging time per day increasedwith increasing ambient temperatures and levels of solar radiation, as well as with […]

Breeding range extensions for the Pacific Golden-Plover andBlack-bellied Plover on the Alaska Peninsula

American Golden Plover (Pluvialis dominica) Science Article 4 abstract To determine whether Pacific Golden-Plovers Pluvialis fulva and Black-bellied Plovers P. squatarola werenesting on the Alaska Peninsula, we conducted field surveys at several sites in 2004. We found both taxa breedingon the peninsula, with fulva in greater abundance. Our findings indicate that fulva nest from at […]

Taxonomy, distribution, and evolution of golden plovers (pluvialis dominica and pluvialis fulva)

American Golden Plover (Pluvialis dominica) Science Article 5 abstract A discriminant function analysis of specimen measurements separates 96% of two forms of Lesser Golden Plover in breeding plumage, previously described as subspecies. The forms breed sympatrically in northwest Alaska and are not isolated by habitat, but the incidence of specimens phenotypically intermediate between the two […]

Morphometric features of Pacific and American Golden-Plovers withcomments on field identification.

American Golden Plover (Pluvialis dominica) Science Article 2 abstract We measured linear dimensions and evaluated identification criteria in Pacific and American Golden-Plovers(Pluvialis fulva and P. dominica) captured for banding. Most of the fulva sampled were wintering birds inHawaii, representative of the mid-Pacific flyway; additional fulva and all dominica were from breeding groundson the Seward Peninsula, […]

Male Incubation in Wilson’s Plover (Charadrius wilsonia)

Thick-billed Plover (Charadrius wilsonia) Science Article 1 abstract Male incubation, defined as exclusive incubation by the male, is thought to be a necessary step in the evolution of polyandry from monogamy in birds. When the female has time to gather more food, she can lay clutches more rapidly, which may be an advantage under certain […]

Notes on reproduction of the Southern lapwing , in Colombia

Southern Lapwing (Vanellus chilensis) Science Article 1 abstract Despite its wide distribution throughout most of South America, the Southern Lapwing (Vanellus chilensis) remains poorly studied, and even the most basic aspects of its natural history have been only briefly reported. According to Johnsgard (1981) four subspecies are recognized, of which. only cayennensis occurs at the […]

International Single Species Action Planfor the Conservation of theSociable Lapwing

Sociable Lapwing (Vanellus gregarius) Science Article 1 abstract The Sociable Lapwing breeds currently in Kazakhstan and central part of southern (further ‘southcentral’)Russia. Its breeding range includes northern and central Kazakhstan, and in Russiaextends currently from the Orenburg region, across Chelyabinsk, Kurgan, Omsk and Novosibirskregions to the area around Barnaul in the Altai. Within this area […]
