Description

The Malaysian plover is 15 cm (5.9 in) in length. The male can be recognized by a thin black band around the neck; the female has a thin brown band. Its legs are pale. Its voice is a soft ''twit''.

Reproduction

The Malaysian plover lays two to five (mode of three) cryptic

eggs Humans and human ancestors have scavenged and eaten animal eggs for millions of years. Humans in Southeast Asia had domesticated chickens and harvested their eggs for food by 1,500 BCE. The most widely consumed eggs are those of fowl, especial ...

Conservation status

This species is classified as near-threatened with about 10,000 individuals. They are thought to be declining because of infrastructure development and human disturbance. Increased human use of important beach habitat may cause trampling of eggs or chicks and also force adults off of nests so that eggs and chicks are vulnerable to heat stress. A study in the Gulf of Thailand suggested that the conversion of short, shrubby, dense vegetation into sparse ''

Sandy tropical beaches have tremendous economic value and as a result there has been intensive development pressure on the remaining Malaysian plover habitats in Thailand. This is likely to continue as the Thai economy continues to improve from the Asian financial crisis and the domestic tourist market expands. The main remaining large populations of Malaysian plovers in Thailand are in

A study published in 2006 attempted to assess the impact of tourism on the species through a large-scale survey in Prachuap Khiri Khan and Petchburi, Thailand; 193 adults and 191 chicks were color-banded as part of the study. The study concluded that "tourism development on Thai beaches affects both habitat availability and productivity of Malaysian plovers by enhancing beach erosion rates, converting medium vegetation into tall monocultures and intensifying human disturbance. These direct effects of habitat loss may be exacerbated by density-dependent reductions in productivity."
