Located in Mekong delta, Vietnam, Tram Chim national park was nominated by the Provincial Authorities of Dong Thap Province as a site for restoring the original Plain of Reeds ecosystem in 1985 by zoning 5,000 ha as a reserve. In 1992, the Prime Minister issued a special order for prompt action to save the Sarus Crane and the wetland ecosystem of Tram Chim. In 1994 Tram Chim was decreed a National Reserve of 7,500 ha and in 1999 was recognised as a National Park. The site is currently being listed under the Ramsar Convention as international important wetland
The total area of Tram Chim National Park is c.7,740 ha. Canals, totalling 53 km in length, surround and bisect the site creating six habitat management plots. Melaleuca was planted for production in the past and now forms a substantial inundated forest. The site is inundated annually to a depth of 2-3 metres during the wet season. There are 22,000 people living adjacent to the boundaries of the site.
There are more than 300 bird species have been recorded in the park, however many of them are very rare or no longer seen recently. Some species have declined their population rapidly, especially Sarus Crane population has dropped from more 200 birds to less than 20 birds in 10 years. On the other hand, many populations are increasing such as Asian Openbill, Oriental Darter, Cormorants, Egrets, etc. These changing have alarmed scientists and conservationists to consider, we need to understand why it has been happening and how to sustain this unique ecosystem.
Whatever happens, since it was listed as Ramsar site in 2012, Tram Chim national become one of attractive ecotourism destinations. Number of tourists visiting the site to learn the wetland and its birds. To help visitors understand what they going to see there, by this post, we would like to introduce some of birds that easy to see by naked-eyes or binoculars. These birds are also cover most of the "normal seen" at bird santuaries in the Mekong delta areas.
Ardeidae members are easy to see in the park if you travel by boat along canals, , they're resident and can be seen year round. Most of non-birder visitors will be not able to distinguish different among egrets spcies as well as among herons, here are some keys
1 - Egrets are white birds, they have long legs, long neck and uasally stand in flooding grassland, edge of cannal or paddy ricefield. There are 4 species of "white" egrets, Great Egret, Intermediate Egret, Little Egret and Cattle Egret. By its names, you can understand their relative sizes are big, medium and small however you only can tell when they stand together, otherwise no reference!
Little Egret has black bill, yellow feet
Both Great Egret and Intermediate have yellow bill, black legs and feet but the latter has traight neck, black bill tip.
Finally, the Cattle Egret. It is easy to regconise in breeding season when plumage becomes orange however a bit challenge in non-breeding when you see from distance, it looks quite like Intermediate Egret but very short neck. It usually seen on paddy field, on the top of tree or following cows/buffaloes
>>>>>>>> Next for Herons
2 - Herons have shape like egrets but they are not "white", some have grey color (Grey Heron, Black-crowned Night-heron), some have redish color (Pond Herons, Purple Heron). They are also very common and easy to see year round.
Grey Heron - very big, long neck and usually seen along dike/cannal
Purple Heron - like Grey Heron but reddish, thinner neck
Chinese Pond Heron and Javan Pond Heron - very difficult to identify between them except in breeding plumage. Chinese Pond Heron is much more common than the other
Black-crowned Night-heron - this common bird usually seen in flock roosting on the tree during day-time. At night, they fly out to find food
>>>>>>>> Next for Bitterns
3 - Bitterns are small size herons, they are difficult to see unless someone disturbs to make them fly out from bush/grass vegtatation
Yellow Bittern and Cinnamon Bittern - they are very similar but the Yellow Bittern has lighter color, when it flies you should see bi-color on the wings and body
Cinnamon Bitter is more reddish, female looks streaky. It has only one color on the wings when it flies
Striated Heron / Little Heron - Although named heron but its behavior and shape like bitterns

Asian Openbill - This spcies is very common in the park, the population is estimated more than 20,000. They eat Golden Apple Snail so they help to control toxic invasive animal. However its increasing population might affect to other birds and ecosystem.
Painted Stork - Commonly seen at certain time, they come to the park during Novermber to March for feeding. The color looks very attractive as it has lotus color wings
Both Woolly-necked Stork and Lesser Adjutant are rare
Lesser Adjutant has no feather on the neck, looks very big and heavy, sometimes it soar like Raptors.
