Day 4 (December 19): We actually lost of our third day due to the complication of permit. As we thought it is no need special permission for Vietnamese to do survey in Ben Tre, however, the local authorities requested us to talk to police. After a couple hours working for permit, the tide was getting higher, so we decided just to check roost site at some salt-pans. There was not many bird observed, we found Marsh Sandpiper (100+), Common Greenshank (29), Common Redshank (11), Golden Plover (24), Caspian Tern (2). None wader-birds including Little Egret (32), Yellow-vented Bulbul, Olive-backed Sunbird, Plain Prinia, Collared Kingfisher.
Day 5 (December 20): We visited sand-flats belongs to An Thuy commune, Ba Tri district. This is an IBA VN 063 classified by Birdlife International. The beach is using as clam farms, ground is sandy and quite hard for SbS, we thought. This is considered as impact from less sediment due to hydropower dams along Mekong river and especially Ba Lai drain and dykes were built along coastal in this area (?). We spent 4 hours checking around, birds encountered were Golden Plover (150), Far Eastern Curlew (30), Common Greenshank (45), Bar-tailed Godwit (60), Red-necked Stint (230), Sanderling (56), Terek Sandpiper (37), Lesser Sand Plover (250), Kentish Plover (70).
In the end, we birded at the mangroves and found our first near-threatned Black-tailed Godwit (1), Little Egret (7), Great Egret (12), Intermediate Egret (6), Great Heron (1), Little Heron (1), Common sandpiper (2), Blue-tailed Bee-eater (3), Common Myna (2), Pied Fantail (5), Golden-bellied Gerygone (4).
