| Summary: | Tanjung Laboh is located in one out of three Important Bird Areas (IBAs) in Johor
called South West Johor Coast which is very crucial foraging ground for resident and migratory
shorebirds. However, the airfield development plan located in the area have been an issue as it
might disturbed the foraging ecology of the shorebirds. Therefore, it is necessary to analyse the
food resources present and the foraging behaviour of the shorebirds in order to determine the effect
of disturbance towards the shorebirds’ foraging behaviour. Thus, a study was conducted for a
month (July to August 2018) in the mudflat area of Tanjung Laboh to identified the time spent of
foraging, food selection and foraging technique of shorebirds by using direct observation
method. A total of 212 observations were recorded during sampling period. No significant
differences were found in time spent foraging between the bird species, (F = 0.18, p = 0.946).
ASpearmanRankCorrelation proved that there is no significant relationship between the time
spent of foraging and the number of preys taken by each species (R= 0.436, p > 0.05). Based
on observation, fish is the most preferred diet choice among bird species which counts a total
of 57% followed by unknown (20%), worm (19%) and bivalve (4%). Significant correlation
was found between the abundance of bird and the frequency of disturbances (humans, dogs
and vehicles) (p < 0.05) while human contribute to a higher percentage in disruptions towards
the species studied (57.7%). The responses of the birds towards the disturbances were varied
in this study, however the birds tend to choose foraging ground far from disturbance area as
the disturbances might chase birds’ prey away thus reduce their feeding rate. By
understanding how the shorebirds response toward disturbance, the conservation action
can be enforced in the future. |
