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, […]

Featured Photo: Identification of Adult Pacific and American Golden Plovers in their Southbound Migration

American Golden Plover (Pluvialis dominica) Science Article 6 abstract Connors (1983) and Connors et al. (1993) confirmed that American (Pluvialis dominica) and Pacific (P. fulva) Golden-Plovers breeding in sympatry in Alaska are distinct species, a conclusion adopted by the A.O.U. (1993). Distinguishing these two species requires that the bird’s age or plumage class be determined […]

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 […]

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 […]
