Map of Locations (not exact locations of birding spots):


This is a 3 day trip that includes several birding sites around Cambodia such as Bengal Florican Grassland, Tmatboey Ecolodge, Preah Vihear temple and Koh Ker complex or Linga Pura city.

We started our tour from Siem Reap province very early in the morning to Bengal Florican Grassland, which is a seasonally inundated outer-floodplain grassland with some small areas of scrub with our target birds such as Bengal Florican, Pied Harrier, Pin-tailed Snipe, Striated Grassbird, Manchurian Reed Warbler, Oriental Skylark, Painted Stork and other species around that area. We did start a bit early in the season for Bengal Florican but we did try our best to observe the Bengal Florican, however, we had a small chance to see it.

Tmat Boey Ecolodge is the home of two critically endangered species located in the Northern Plain of Cambodia, Giant Ibis and White-shouldered Ibis. Other species include Savanna Nightjar, White-rumped Falcon, Yellow-crowned Woodpeckers, Streak-throated Woodpeckers, Black-headed Woodpeckers, Brown Boobook, and Brown Fish-owl.

After seeing our key birds, we spent a half day visiting the main temple near the Thai border called “Preah Vihear Temple”. Then, we returned to the lodge for lunch and prepared our stuff before checking out. We were leaving from Tmat Boey Ecolodge to Siem Reap town at 1:30 pm. Along the way, we also had a stop at Koh Keh complex, exploring around 2 hours for birds and temples.

Trip Report

Day 1: Bengal Florican Grassland and Tmat Boey Ecolodge

We left early from our hotel in Siem Reap to Bengal Florican grassland on national #6 to the east of Siem Reap, Cambodia. We spent an hour and a half to reach our destination, then met our local guide at Preah Hout Community along the way to the birding spotted area. Even though, the birding tour starts a bit early in the season for the Bengal Florican and also some bird species that have not migrated yet.

We had good weather to observe all the bird around us. We have seen many birds such as Painted Stork, Pin-tailed Snipe, Oriental Skylark, Chestnut Munia, Asain green Bee-eater, Manchurian Reed Warbler and some more species of Starling.

We did bird watching at Preah Hout area for around 3 hours and then we moved to Tmat Boey Ecolodge in Preah Vihear province. We drove for around 5 hours to our next destination, and we had a small break for lunch near Beng Mealea temple for about 30 min.

We reached Tmat Boey Community Ecolodge at 2:30 p.m. Check-in at the lodge and do some rest after a long drive. We met our local guide Mr Chherm and had some discussion about our itinerary. We decided to leave our lodge at 3:00 pm to look for our target bird with our local guide. We walked about 30 mn to the White-shouldered Ibis’s rooting tree because the bridge across the river was broken during the rainy season, and our car could not access the spotted area.

We saw around 18 White-shouldered Ibis at its rooting tree. After seeing the birds, then, we walked back to the car at 6:30 pm and drove back to the lodge to get some rest and dinner at 7 pm.

Day 2: Tmat Boey 

We planned to a bit early to see the Giant Ibis at its nesting tree, so, we left the lodge at 5:30 am. We drove about 20 min to the site but we had issues reaching the spotted area in our 4×4 car due to roads damaged in the wet season. So, we had to walk about 20 min to see the Giant Ibis.

We had a beautiful time observing Giant Ibis with their small chick in the nest for about 20 min, then, we looked around the area to find a good place to set up our breakfast. Along the way to the Giant Ibis’s nest, we see many birds such as Rufous-winged Buzzard, Common Flameback, Green Imperial Pigeon, Shikra, Small Minivet, White-rumped Munia, and Nuthatch species. After seeing our key bird species, we moved to other places and looked for the White-rumped Falcon. Luckily, we did see 3 of the White-rumped Falcon.

In the afternoon time, we left at 3:00 pm to go to the site called Phnom Raeng for other key birds such as Rufous-bellied Woodpecker, Rufous-bellied Woodpecker, Streak-throated Woodpecker, and Savana Nightjar.

When we arrived in the area, we felt so quiet from the nature. We keep walking along the trail to find our key species. We found Rufous-bellied Woodpecker, Black-hooded Oriole, White-browed Fantail, Large Cuckooshrike, Burmese Shrike, Rufous Woodpecker, and Savanna Nightjar. After exploring around about 3 hours, we walked back to the car and returned to the lodge. Refreshing with shower and dinner at 7:00 pm.

Day 3: Tmat Boey, Preah Vihear Temple, Koh Ker Temple and Siem Reap

At 5:30 am, we left the lodge and drove about an hour and half to the foothill of Preah Vihear temple. We did arrive there at 7:30 am, and we had breakfast because the ticket booth was not open yet. So, we had breakfast there and did some bird watching around that area.

The ticket booth was opened at 8:00 am, then we went up the clip of Dong Raek mountain for our temple tour. Along the way, we did birdwatching and saw a target bird of our client, Black-hooded Bulbul, and other warblers, sunbirds, and flowerpecker species.

After visiting the temple, we returned to the lodge and arrived back at 10:30 am, had a break, refreshed with shower, and had lunch at noon. At 1:30 pm, we left the lodge to visit our last temple called “Koh Ker” a new world heritage site that had just registered with UNESCO.

We spent an hour and a half exploring this ancient city and found another key bird for our client. Black-headed Woodpecker was a lifer for our client at that time because we tried many places near Tmat Boey Lodge and looked for it but we did not see it, so, our last spotted area and was our last chance to find it. Finally, we saw them and some other species such as minivets, bulbuls, nuthatches, woodshrikes etc.

After bird watching around Koh Ker Complex, we visited the main temple called Koh Ker temple for about an hour.

After the temple, we went back to Siem Reap town directly, nonstop because the traffic was a bit busy during the water festival. Drop off the clients at Yi’s family homestay outside the Siem Reap town.
