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 […]

Breeding of the Semipalmated Plover (aegialitis semipalmata) inYarmouth County, Nova Scotia.

Semipalmated Plover (Charadrius semipalmatus) Science Article 3 abstract On June 14, 1920, at Cook’s Beach,at the mouth of the Chebogue River, Yarmouth County, Nova Scotia, I found a nest and four eggs of the Semipalmated Plover (aegialitis semipalmata(Bonap.))

BREEDING RECORD FOR THE SEMIPALMATEDPLOVER AT OCEAN SHORES, WASHINGTON

Semipalmated Plover (Charadrius semipalmatus) Science Article 4 abstract On 23 June1 973, at Ocean Shores,Grays Harbor County, Washington, Eugene Hunn and I observed an adult Semipalmated Plover (Charadrius semipalmatus) in breeding plumage calling incessantly and diving at us as close as 15 feet. The bird seemed to be defending a territory in a flat sandy […]

Influence of Arctic Terns on Survival of Artificialand Natural Semipalmated Plover Nests

Semipalmated Plover (Charadrius semipalmatus) Science Article 2 abstract Survival of Semipalmated Plover (Charadrius semipalmatus) nests was compared in areas with andwithout nesting Arctic Terns (Sterna paradisaea) to determine whether the protection provided to plovers by associationwith this colonial species is passive or aggressive. Artificial and natural nests placed=100 m from terns hadsimilar rates of survival […]

Predicting the population consequences of human disturbance for Ringed Plovers Charadrius hiaticula: a game theory approach

Ringed Plover (Charadrius hiaticula) Science Article 2 abstract Human disturbance and its potential impacts upon bird populations are currently topical and contentious issues for conservationists. Although many studies have revealed a behavioural impact, or even direct effect on breeding success or survival, these cannot usually be extended to predict the impact on population size. Here […]

Different timing of autumn migration of two Ringed Plover Charadrius hiaticula subspecies through the southern Baltic revealed by biometric analysis

Ringed Plover (Charadrius hiaticula) Science Article 1 abstract Ringed Plovers were trapped in Puck Bay (southern Baltic) between 1983 and 2002 during autumn migration. In adults a clear decrease of mean wing and bill lengths occurred between the third decade (ten-day period) of July and the first decade of August. A similar pattern was observed […]

Provision of nest cages to reduce little ringed plover Charadrius dubius nest predation at Welney, Norfolk, England

Little Ringed Plover (Charadrius dubius) Science Article 2 abstract At a site in eastern England, wire mesh cages were placed over little ringed plover Charadrius dubiusnests to protect their eggs from predation. The adult birds continued incubating their eggs and no nestdesertions were attributed to cage placement. Protection with cages resulted in an increase inproductivity, […]

Do northern lapwings Vanellus vanellus and little ringed ploversCharadrius dubius rely on egg crypsis during incubation?

Little Ringed Plover (Charadrius dubius) Science Article 1 abstract We studied the possible role of clutch crypsis in antipredator behaviour in tworelated species of ground-nesting waders with camouflaged eggs, the northern lapwing (Vanellusvanellus) and the little ringed plover (Charadrius dubius). We examined whether this behaviourappears regularly in both species and tested the difference in the […]
