I visited Ang Trapeang Thmor last week for several days. Water levels are still very high. We also had a spell of rain and cool, overcast weather for a day, which was a nice relief from the increasing heat.
Birding highlights were:
Greater Painted Snipe (2, one male and one female seen on different days in different locations)
Common Coot, 2
Himalayan cuckoo, 1
Ruddy-breasted Crake (1 crossing the dam at dusk)
Black-winged Stilts (group of around 30 flying from "WCS wetland" towards the reservoir)
Eastern Marsh and Pied Harriers (photo below is of what I believe is a female Pied, confusion with Western Marsh Harrier is possible if only seen well from above)
Greater Spotted Eagle (at least 1 seen on different days)
Kestrel (1 female, probably Common)
Chestnut-tailed Starling (2, along southern dam wall) - I don't know if this species has been recorded at ATT before? A pair was nesting in a pylon as I've observed them do in Takeo.
And of course Sarus Cranes! with the largest number seen at a single location being 139.
It was great to occasionally stumble on groups of Eld's Deer in the area north of the reservoir (a group of 15 seen on one day)
