Foraging ecology of birds in mudflat area of Tanjung Laboh, Johor

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 fora...
