Lesser migratory birds have been visiting Manila Bay, a region known to host one of the largest concentrations of migratory waterfowls in the Philippines during migration season. This has been so in the last two years, ironically, when its waters are evidently cleaner, or at least physically—without the floating garbage near the shores. The latest Asian Waterbird Census in Manila revealed that the January 2021 count tallied 110,000 waterbirds, and of the 60 species observed, over two-thirds are migratory birds that came from as far as Siberia and Alaska.
