A study was conducted to determine the diversity and
abundance of shorebird species habituating the mudflat area of Jeram
Beach and Remis Beach, Selangor, Peninsular Malaysia. Direct
observation technique (using binoculars and video camera) was
applied to record the presence of bird species in the sampling sites
from August 2013 until July 2014. A total of 32 species of shorebird
were recorded during both migratory and nonmigratory seasons. Of
these, eleven species (48) are migrants, six species (26) have both
migrant and resident populations, four species (17) are vagrants and
two species (9) are residents. The compositions of the birds
differed significantly in all months (χ2 84.35, p < 0.001). There is a
significant difference in avian abundance between migratory and
nonmigratory seasons (MannWhitney, t 2.39, p 0.036). The
avian abundance were differed significantly in Jeram and Remis
Beaches during migratory periods (t 4.39, p 0.001) but not during
nonmigratory periods (t 0.78, p 0.456). Shorebird diversity was
also affected by tidal cycle. There is a significance difference
between high tide and low tide (MannWhitney, t 78.0, p < 0.005).
Frequency of disturbance also affected the shorebird distribution
(MannWhitney, t 57.0, p 0.0134). Therefore, this study
concluded that tides and disturbances are two factors that affecting
temporal distribution of shorebird in mudflats area.
