Ream is thought to be one of the key sites in Southeast Asia for the brahminy kite, with a
breeding population of this charismatic regionally-threatened species. The density of
brahminy kite over Ream’s six estuary zones was estimated at 0.71 birds per Ha.
Our population density estimates for brahminy kite can be broken down into zones to
facilitate an examination of the particular features of the estuary that support this bird
population (see figure 6). Zones two and three contain by far the densest populations of
brahminy kite. The population of brahminy kites visible over the estuary also varies
according to the time of day (see figure 7) and water level (measured by time since low tide;
see figure 8). Brahminy kites tend to be seen over the estuary around the middle of the day
and at low water, i.e. up to one hour after low tide.
